UK police know the whereabouts of Julian Assange, the head of WikiLeaks, according to a report in British newspaper The Independent.
The hacker-turned-journalist is wanted for questioning in Sweden over allegations of rape and sexual molestation.
According to the report, the Australian's legal team have been in contact with officers at Scotland Yard ever since he arrived in the UK in October.
Assange's UK lawyer, Mark Stephens, denied that his client was in hiding, but associates have refused to reveal his whereabouts after a number of public calls have been made for his assassination.
Britain's Serious Organised Crime Agency (SOCA) has received the international arrest warrant or 'Red Notice' issued yesterday by Interpol, but has so far refused to authorise the Assange's arrest.
The Independent reports that the delay in arresting Assange is "said to be a technical one", with SOCA seeking clarification over the European Arrest Warrant issued last month by Swedish prosecutors.
Assange's legal team this morning lost their appeal in Sweden's Supreme Court, upholding the detention order issued last month by a lower court on Stockholm.
