London (CNN) -- An appeal by Swedish authorities against the decision to grant bail to WikiLeaks founder Julian Assange will take place Thursday at the High Court in London, a spokesman said.
The court did not specify a time.
Assange handed himself over to London police last week to answer a European arrest warrant from Sweden, which wants to question him over alleged sex crimes.
He was granted bail Tuesday, but he remained behind bars because a lawyer for Swedish prosecutors immediately filed an appeal.
Assange is facing accusations of rape, sexual molestation and illegal use of force stemming from separate incidents in August in Stockholm. He could be sentenced to two years in prison if convicted. He has not been charged with a crime.
His lawyers deny the allegations and have vowed to fight any attempts at extradition. CNN
