WikiLeaks has accused the Ecuadorean embassy of spying on their founder Julian Assange, with Spanish police now investigating an extortion attempt threatening to publish sensitive documents.

The organisation’s editor-in-chief says he met a group in Spain threatening to publish private legal documents, video, audio and photos unless they were paid three million euros.

The news comes after recent reports that the Australian may soon be evicted from Ecuador’s London embassy which he has sought refuge in since 2012.

The embassy has not yet responded to the allegations which Reuters is still unable to confirm.
