The WikiLeaks founder is accused of leaking an embarrassing snap of Ecuadorian premier Lenin Moreno dining on a platter of lobster in bed in a luxury hotel room.
Mr Moreno was so furious at the breach that he ordered Assange's seven-year refuge at the embassy be ended on Thursday, the Mail on Sunday reports.
The silver-haired hacker was booted out of his Knightsbridge safe haven after being handcuffed by embassy security and dragged out by officers from Scotland Yard.
The picture, which has been widely circulated on Twitter, comes at an awkward time for the president whose administration has the Ecuadorian people living under austerity measures.
Mr Moreno claimed Assange leaked the photo along with more than 200 private emails and text messages belonging to the president and his wife to website INApapers.org.
