WikiLeaks founder Julian Assange was scheduled to appear in a London court Tuesday seeking to fight his extradition to Sweden in a sex-crimes investigation and trying to secure bail after being held for a week in a British prison.

The 39-year-old Australian was ordered held in custody by a judge at a hearing a week ago after surrendering himself to Scotland Yard to answer a Swedish arrest warrant. Assange's attorneys maintain that their client is innocent and that Western governments are exploiting the false charges to silence WikiLeaks.
