A Swedish appeals court rejected on Thursday, Nov 20, an appeal by WikiLeaks founder Julian Assange to revoke a detention order issued by prosecutors in 2010 over allegations of sexual assault, Reuters reported.

"In the view of the Court of Appeal there is no reason to set aside the detention solely because Julian Assange is in an embassy and the detention order cannot be enforced at present for that reason," Svea Court of Appeal said in a statement.

Assange has been stuck inside Ecuador's London embassy since June 2012 to avoid a British extradition to Sweden. The country wants to question him on allegations of sexual assault and rape, which he denies.

The Australian says he fears that if Britain extradited him to Sweden he would then be extradited to the United States where he could be tried for one of the largest information leaks in U.S. history.
