Julian Assange, Wikileaks Founder Arrested
Mr Assange, 40, whose conditions included staying at his bail address between 2200 and 0800 BST, spent Tuesday night at the embassy.
Last week he failed to reopen an appeal against his extradition to Sweden.
Mr Assange, wanted for questioning in Sweden over rape and sexual assault allegations, denies any wrongdoing.
Ecuador had said it was “studying and analysing” Mr Assange’s request for asylum.
