British police arrested WikiLeaks founder Julian Assange Tuesday on a European warrant issued by Sweden, London's Metropolitan Police said.

Swedish prosecutors issued the arrest order for the 39-year-old Australian who is wanted in Sweden on suspicion of committing sexual crimes, which he denies.

His lawyer had earlier arranged to deliver him to British police for questioning in a sex-crimes investigation of the man who has angered Washington by spilling thousands of government secrets on the Internet.

Lawyer Mark Stephens told reporters in London that London's Metropolitan Police had called him to say they had received an arrest warrant from Sweden for Assange. Assange has been staying at an undisclosed location in Britain.

"We are in the process of making arrangements to meet with the police by consent in order to facilitate the taking of that question and answer that is needed," Stephens said Monday.

The 39-year-old Australian is wanted on suspicion of rape, sexual molestation and unlawful coercion in Sweden, and the case could lead to his extradition.

Amid Assange's personal legal troubles, his WikiLeaks site continued to reveal state secrets. (msnbc.com news services)
