Inspector Russell Dew, 44, based at Mansfield police station, is accused of sexual activity with a child in Newark, Nottinghamshire, over the past year.
The officer was arrested on Thursday and will appear at Sheffield Magistrates' Court on Monday.
The BBC understands the alleged victim was 13 years old at the time of the offences.
Julian Assange said his extradition would breach his human rights Swedish prosecutors have said statements by two women who have accused Wikileaks founder Julian Assange of sexual assault show they did not consent to sex.Their lawyer told the High Court that Mr Assange faced genuine accusations of "non-consensual, coerced sex".
Lawyers representing Mr Assange said the women had consented to intercourse with the Australian.
They have asked the High Court to block his extradition to Sweden.
Mr Assange's appeal challenges a ruling at Belmarsh Magistrates' Court in February, which said extradition would not breach his human rights.
At that court, District Judge Howard Riddle concluded Mr Assange would get a fair trial if he was ever charged.
The 40-year-old computer expert is wanted for questioning on three allegations of sexual assault and one of rape, said to have taken place in Stockholm in August last year.
The claims were made by two female Wikileaks volunteers.
'Non-consensual'Clare Montgomery QC, appearing for Swedish prosecutors on the second day of the High Court hearing, said it was "perfectly plain" the women "did not freely consent without coercion".
She said they consented "already having been trapped into a position where they had no choice".
They had "let him continue", said Ms Montgomery.
"This is non-consensual. It is coerced, and the words used - 'I let him' - means non-consent," she told Lord Justice Thomas and Mr Justice Ouseley.
Ms Montgomery said the first woman, named in court as AA, had been a victim of "coercive violent sex" and Mr Assange had "broken a condom".
"Consent had only been given to protected intercourse," she said.
She told the court Mr Assange had raped the second woman, referred to in court as SW, while she was asleep.
Ms Montgomery said the woman may later have agreed to let Mr Assange continue but this did not change the earlier act of rape.
But Ben Emmerson QC said the women had consented and his client would not have been charged with a sexual offence under English law.
"What (Swedish prosecutors) must prove beyond reasonable doubt is that if these circumstances, as alleged, had happened in London, would they have constituted offences?" he said.
'Politically motivated'Mr Assange says the case is politically motivated, as his website has leaked a mass of sensitive US diplomatic cables.
His lawyers say the claims against him are not extradition offences, and sending him to Sweden would be an abuse of process breaching his human rights.
Mr Emmerson has said the arrest warrant was "flawed" as it failed to fairly describe the claims against Mr Assange.
Mr Assange fears extradition to Sweden may lead to him being sent to the US to face separate charges relating to Wikileaks, for which he could face the death penalty.
The Australian won bail in December and has been staying at Ellingham Hall, a 10-bedroom Norfolk farmhouse owned by Vaughan Smith, director of the Frontline media club.
His bail conditions include wearing an electronic tag and daily appearances at a nearby police station.
Supporters had gathered outside the High Court for Mr Assange's arrival.
Judges told Nat Fraser will face a retrial for murder before he was remanded Elgin businessman Nat Fraser has had his conviction for the murder of his estranged wife Arlene overturned but will face a retrial.Mr Fraser was jailed in 2003 after his wife went missing in Moray five years earlier. Her body was never found.
In May, the UK Supreme Court remitted the case to the Court of Criminal Appeal in Edinburgh to decide on a retrial and to quash the conviction.
Judges at the Appeal Court in Edinburgh granted the application for a retrial.
The 52-year-old was remanded in custody following the decision.
The case began on 29 April 1998 when wife Arlene, 33, waved her two young children, Jamie and Natalie, off to primary school and then disappeared.
Mr Fraser appealed for her to get in touch but was later tried and jailed for a minimum of 25 years.
Arlene Fraser went missing from her Moray home in 1998 He lost an appeal against his conviction in 2008 but pursued his case to the UK Supreme Court in London after he exhausted all avenues in Scotland.
The Supreme Court found that Mr Fraser's human rights may have been breached because prosecutors failed to disclose some evidence in the case against him.
They returned the case to the Appeal Court in Edinburgh.
After consideration, Scotland's top judge, the Lord Justice General Lord Hamilton, sitting with Lords Reed and Carloway, formally overturned Mr Fraser's conviction.
The three judges granted authority for a fresh prosecution after being urged to do so by advocate depute Alex Prentice QC.
No date has been set for Mr Fraser to return to court.
In a speech on Wednesday he will say banks must be set up so that their High Street branches and savings and loans would not be damaged if their trading arms ran into trouble.
The legal separation of the functions of big banks was recommended by the Independent Commission on Banking.
He will also announce the privatisation of Northern Rock.
The former mutual was nationalised in February 2008, in the early stages of the financial crisis.
The BBC's business editor, Robert Peston, said the changes would represent "the most significant reform to our banking system since Big Bang in 1986 made it much easier for our giant banks to buy stock brokers and become huge in investment banking".
More protectionIn his annual Mansion House speech, Mr Osborne will also say that banks should have to hold more capital to protect themselves against future losses than the new international minimum of 7% of their risky assets.
He will not put a figure on what minimum he will impose, but Treasury sources said that 10% would be "the right ballpark".

Robert Peston Business editor, BBC News The 10% minimum was another recommendation of the Independent Commission on Banking (ICB) in its interim report in April.At the time, Mr Osborne welcomed the report, but he has not previously endorsed its findings.
The shadow chancellor, Ed Balls, has also given the commission his backing.
"To protect customers and taxpayers we need tough accountability and transparency and clear, workable and robust firewalls," he said.
The commission's final report, which is expected to give details of how banks' firewalls will work, is due to be published on 12 September.
The chancellor will announce in his speech how he plans to relinquish state control of Northern Rock.
The former mutual has been split into a "good bank", containing customers' savings and about 70 branches, and a "bad bank" containing the more toxic loans.
The former is set to be sold, while the latter will continue to be owned by the Treasury.
However, Mr Balls called for Northern Rock to be mutualised rather than sold off, and accused Mr Osborne of failing to give the option serious consideration.
DisagreementAccording to Robert Peston, the purpose of ring-fencing is to ensure that in a major crisis "a retail bank could be hived off and saved by the Bank of England at less cost to taxpayers, because the investment banking part of the same bank would be allowed to fail".
"The minutiae of how retail banking operations are to be insulated from investment banking are yet to be worked out. The practical and legal challenges are formidable."
Angela Knight of the British Bankers' Association conceded that the banks had different views on how this should be done.
"There's a lot of issues and a lot of details that needs to be thought through and discussed," she said.
Stephen Hester, chief executive of the semi-nationalised Royal Bank of Scotland, told MPs last week that putting retail banks into separate subsidiaries could increase the riskiness of the banking system and put up costs for banks and their customers.
But the boss of HSBC, Doug Flint, told the same committee hearing that ring-fencing was a good idea.

"While [ring-fencing] is intellectually a sound move, the problem is that in practice, with the pressures of the real world, the ring fence will not be completely... watertight," said Lord Lawson, who was Chancellor of the Exchequer under Margaret Thatcher.
"I'm quite sure the banks would like them to be permeable."
Speaking to BBC Radio 4's Today programme, he said there would need to be two totally different cultures - "prudence and caution" in retail banking, and a "go-go" culture in investment banking.
"If investment bankers make a mistake, they should go bust," he said, and it was "absolutely intolerable" that they could be bailed out along with the retail banks.
Subsidy removedThe reforms are not expected to make the UK banking system completely risk free, according to Alistair Milne of the Cass Business School.
"I don't think anybody on the Vickers Commission thinks [ring-fencing] is a magic solution that will make all potential banking problems go away," he told the BBC, although he said it would make High Street banking safer.
Instead, Mr Milne said it was about "removing the clear subsidy that has existed in the past" that enabled banks to "borrow cheaply on the basis of having all their retail activities, and use that for quite risky business".
However, removing this subsidy will not be cost-free for banks' customers, according to banking analyst Ralph Silva of SRN Research.
"Bottom line - the price of the products is going to go up for everyone in the UK," he told the BBC, estimating that the increase in cost for customers would be 10-15%.
The document was written by civil servants in 2006 at a time when Ed Balls was on the backbenches A document by civil servants urging spending restraint from the Labour government in 2006 is among more of Ed Balls' leaked, private papers published by the Daily Telegraph.The file was written when Tony Blair was PM and Mr Balls was a backbencher.
The Conservatives said the latest revelations showed Labour had taken a "reckless" approach to the economy.
Current shadow chancellor Mr Balls said whoever was using his private papers had clear political motives.
He accused them of misrepresenting the papers' contents.
The latest document published by the Telegraph put forward ideas for savings ahead of the Comprehensive Spending Review of 2007.
It suggested that departmental spending increases above inflation ought to become the exception not the rule.
The Conservatives claim this advice was "recklessly" ignored.
Economy claimsBut Labour says that, at the time, the Conservatives were committed to matching their spending plans and the then chancellor Gordon Brown was running a lower deficit than he had inherited.
Mr Balls has accused the Conservatives of trying to "rewrite history" and sensationalising the contents of the leaked papers.
He said: "Once again the headlines and allegations are not remotely substantiated by either the content of the documents or the reality of what happened."
Former foreign secretary David Miliband has shown no interest in returning to front-line politics Mr Balls added: "However much the Conservative Party and their supporters sensationalise these papers, and try to rewrite history, their allegations are not borne out by reality."
BBC political correspondent Iain Watson says the biggest issue in British politics is not simply the size of the deficit and how quickly to reduce it, but how it was caused.
Labour blames increased spending in its latter years in office on the international financial crisis, he adds.
The Conservatives aim to portray the party as inherently profligate - and therefore not to be trusted with running the economy.
Our correspondent says the latest leak is not merely of interest to political historians but plays directly into current political debate.
Hit backMeanwhile, the Guardian says it has obtained a final draft of a speech that former foreign secretary David Milband planned to deliver if he had won the Labour leadership race - instead of his brother, Ed.
The paper says he would have told Labour's conference that the party's greatest danger lay in underestimating the challenge of the deficit, and that it was vital to regain the public's trust on the economy.
Mr Miliband has not spoken about sensitive domestic issues since his defeat last September.
Disclosure of the speech came separately to leaked memos published in the Daily Telegraph on Friday, detailing plans within Labour to have Gordon Brown succeed Tony Blair as prime minister from 2005.
Mr Balls hit back, saying it was "not true" to say he and Mr Brown had plotted to oust the prime minister.
The newspaper obtained more than 30 memos belonging to Mr Balls, who was one of Mr Brown's closest advisers.
The documents are believed to have disappeared from the Department for Education - Mr Balls' former department - during last year's general election.
The Cabinet Office is looking into whether there were any "breaches of document security within government".
Mr Flint said HSBC was committed to improving investor returns HSBC bosses faced shareholder anger over lacklustre returns and high executive pay, at the bank's annual general meeting.Chairman Douglas Flint admitted that shareholder returns had been disappointing and inadequate.
A fifth of investors refused to back the bank's remuneration plan, marking stronger opposition over pay than that faced by other banks in the UK.
Under the plan, chief executive Stuart Gulliver could earn up to ?12.5m.
The remuneration report contained new arrangements for paying board members in the wake of protests at last year's shareholder meeting.
But some investors at this year's meeting were still unhappy.
"How greedy is this board of directors?" asked private shareholder Michael Mason-Mahon.
Ahead of the AGM, both share advisory group Pirc and the Association of British Insurers had raised concerns about the scheme.
But another institutional investor, Standard Life - which had been one of the bank's fiercest critics over executive pay last year - backed the plan.
Libya questions
Mr Gulliver became chief executive earlier this year and stands to earn up to ?12.5m in 2011 Earlier this month, HSBC revealed details of a large cost-cutting programme, aimed at saving up to $3.5bn (?2bn; 2.4bn euros).
The programme involves a retreat from retail banking, although the number of job cuts that will be made has not yet been disclosed.
It could also involve HSBC, which is Europe's biggest bank, selling its US credit card business.
At the meeting, the bank also faced questions over its relationship with the Libyan government and leader Muammar Gaddafi, after a leaked report earlier this week named HSBC, together with other well-known institutions, as holding Libyan state funds.
Mr Flint said Libya had been rehabilitated by the international community in 2006, which was why it had access to the international financial system again, before being cast aside this year.
But he refused to be drawn on whether HSBC had any connection to the Libyan government.
Scott Raisbeck has been told he faces a jail term A man faces being jailed after admitting he helped gunman Raoul Moat by hiding evidence. Scott Raisbeck, 30, removed the van Moat used when he shot his ex-girlfriend and killed her new partner.
Appearing at Newcastle Crown Court, Raisbeck pleaded guilty to perverting the course of justice and handling stolen goods.
He was bailed for pre-sentence reports and will appear again in June.
Mr Justice Coulson said: "It is important for you to understand I will impose a prison sentence on you.
"The pre-sentence report is to get an idea of the appropriate period."
The court heard that Raisbeck hid a stolen white van used by Moat, and removed evidence from it, so the gunman could evade the police.
In March, two other men, Karl Ness and Qhuram Awan, were jailed for life for helping Moat in July.
During his rampage, Moat's former girlfriend Samantha Stobbart was seriously injured and karate instructor Chris Brown was killed.
Moat also shot Pc David Rathband in the face, leaving him blind.
Following the shootings Moat went on the run for a week, sparking a major manhunt, and then shot himself in Rothbury, Northumberland.
