As you probably know, Assange is wanted in the U.S. for allegedly using WikiLeaks as a conduit for Russian leaks. The specific charges under which he was arrested are as yet unknown. Via the Washington Post:
PARIS — Ecuador handed Julian Assange over to British authorities Thursday, ending a standoff that left the controversial WikiLeaks founder holed up in the Ecuadoran Embassy in London for nearly seven years.
Video of the arrest showed a gray-bearded Assange being pulled by British police officers down the steps of the embassy and shoved into a waiting police van. Assange appeared to be physically resisting. His hands were bound in front of him.
Ecuador, which took Assange in when he was facing a Swedish rape investigation in 2012, said it was rescinding asylum because he of his “discourteous and aggressive behavior” and for violating the terms of his asylum.
The British government heralded the development. “Julian Assange is no hero and no one is above the law,” Jeremy Hunt, Britain’s foreign secretary, wrote on Twitter. “He has hidden from the truth for years.”
