Wikileaks co-founder Julian Assange has been arrested at the Ecuadorian embassy in London, the BBC reports.
Mr Assange took refuge in the embassy seven years ago to avoid extradition to Sweden over a sexual assault case that has since been dropped.
The Met Police said he was arrested for failing to surrender to the court.
Ecuador's president Lenin Moreno said it withdrew Mr Assange's asylum after his repeated violations of international conventions.
But Wikileaks tweeted that Ecuador had acted illegally in terminating Mr Assange's political asylum "in violation of international law".
