From the BBC:
The founder of the whistle-blowing website Wikileaks, Julian Assange, has been arrested by police in London [as noted by David in the comments, he handed himself in for questioning - ATD].
The 39-year-old Australian, who was the subject of a European arrest warrant, denies allegations he sexually assaulted two women in Sweden.
Mr Assange is due to appear at City of Westminster Magistrates' Court later.
A Wikileaks spokesman said Mr Assange's arrest was an attack on media freedom but it would not stop the release of more secret files.
Scotland Yard said Mr Assange was arrested by appointment at a London police station at 0930 GMT.
Mr Assange is accused by the Swedish authorities of one count of rape, one of unlawful coercion and two counts of sexual molestation, alleged to have been committed in August 2010.
The Independent continues:
Police contacted [Assange's lawyer] last night after receiving a fresh European Arrest Warrant from the Swedish authorities.
The first warrant, issued last month, was not valid as officials had failed to fill in the form properly.
Detectives in Sweden want to question Mr Assange after two women claimed they were sexually assaulted when he visited the country in August.
Solicitor Mark Stephens said his client was keen to discover what allegations he was facing so he could clear his name.
He said: "It's about time we got to the end of the day and we got some truth, justice and rule of law.
"Julian Assange has been the one in hot pursuit to vindicate himself to clear his good name.
"He has been trying to meet with her (the Swedish prosecutor) to find out what the allegations are he has to face and also the evidence against him, which he still hasn't seen."
