(AP Photo/Keystone, Martial Trezzini, File) (Newser) – Julian Assange has surrendered to London authorities, who have arrested him on a Swedish warrant for suspicion of sex crimes. His lawyer arranged to deliver the controversial WikiLeaks founder to police for questioning. The 39-year-old Australian is wanted on suspicion of "sex by surprise," sexual molestation, and unlawful coercion in Sweden. The case could lead to his extradition. He's due to appear in Westminster Magistrate's Court later today. Assange is being held at an undisclosed location, and he was been hiding out somewhere in Britain at least since last week, reports the AP.
