The Australian was dragged out of the embassy last month and is serving a 50-week prison sentence for bail violations.
He faces an extradition request from the US next month.
«On Monday, Ecuador will perform a puppet show at the embassy of Ecuador in London for their masters in Washington, just in time to expand their extradition case before the UK deadline on 14 June. The Trump administration is inducing its allies to behave like it’s the Wild West,» said Kristinn Hrafnsson, editor in chief of WikiLeaks, on Sunday.
Baltasar Garzon, international legal co-ordinator for the defence of Assange and WikiLeaks, has urged international bodies to intervene in what he called «an unprecedented attack on the rights of the defence, freedom of expression and access to information».
«It is extremely worrying that Ecuador has proceeded with the search and seizure of property, documents, information and other material belonging to the defence of Julian Assange, which Ecuador arbitrarily confiscated, so that these can be handed over to the the agent of political persecution against him, the United States,» Garzon said.
