WikiLeaks founder Julian Assange has been arrested in London, the Wall Street Journal reported early Thursday, citing a U.K. police briefing. The police say they were invited into the embassy in London, where Assange has been a resident for seven years, by Ecuador's government, which withdrew asylum. Assange is being held at a central London police station, according to the report. He took refuge in the embassy in 2012 while on bail in the U.K. over sexual-assault allegations against him in Sweden. Assange had claimed that if he were extradited to Sweden he might be arrested by the U.S. and face charges relating to the WikiLeaks publication of U.S. diplomatic correspondence. WikiLeaks also is the subject of U.S. probes into its 2016 election role. Ecuador's president has said Assange "repeatedly violated" the conditions of his asylum at the country's London embassy.
