Assange was wanted by British police for skipping bail in August 2012, while he was under investigation for sexual assault and rape in Sweden.
London’s Metropolitan Police said the Ecuadorian government had withdrawn asylum for Assange, adding that officers had been “invited into the embassy by the ambassador.”
Footage shot by the Ruptly news agency showed a bedraggled Assange being carried out of the building by seven men.
As he was bundled into a waiting police van, Assange shouted: “You must resist. You can resist … the U.K. must resist.”
