British police arrested Wikileaks founder Julian Assange on Thursday. He had been hiding in the Ecuadorian Embassy in London since 2012 and was arrested after the Ecuadorian government invited the Metropolitan Police Service into the embassy to remove him. Assange was initially arrested for jumping bail in 2012, but the Metropolitan Police Service subsequently announced that he had been "further arrested on behalf of the United States authorities."

After Assange's arrest, the US Justice Department unsealed its indictment against him. The indictment focuses on Assange's role in helping Chelsea Manning steal classified information from the US military.
