British police have arrested WikiLeaks founder JULIAN ASSANGE on a European warrant issued by Sweden for his alleged sex crimes. reports that the controversial 39-year-old Australian — who’s accused of rape — was arrested at 9:30 a.m. local time (4:30 a.m. ET) Tuesday, after he surrendered to police in London.

An attorney for Assange  had earlier arranged to deliver him to British police for questioning in the sex-crimes investigation.

He was wanted on suspicion of rape, sexual molestation and unlawful coercion in Sweden, and the case could lead to his extradition back there.

The allegations leveled against him involve two women he met in Sweden over the summer.

 Assange is accused of rape and sexual molestation in one case and of sexual molestation and unlawful coercion in another.

He’s scheduled to appear at City of Westminster Magistrate’s Court Tuesday later this afternoon.

Assange flatly denies the allegations, which his attorneys claim comes from a "dispute over consensual, but unprotected sex."

His lawyers also said the Swedish investigation has turned into a "political stunt."

Interpol placed Assange on its most-wanted list on November 30, after Sweden issued the arrest warrant. Last week, Sweden’s highest court upheld the detention order.

Assange’s attorney Jennifer Robinson said the WikiLeaks founder had voluntarily offered to cooperate with Swedish prosecutors because he "is very keen to clear his name," but his offers have been refused.

As The ENQUIRER reported yesterday Assange has threatened to release "Doomsday Files" which are  super-encrypted top-secret trojans that would imperil the fragile diplomatic ties around the world.

A British judge has denied  Assange bail  after the WikiLeaks founder told a London court he would fight efforts to extradite him to Sweden to face a sex-crimes investigation.
