Egypt has asked Cyprus to extradite the man accused of hijacking an airliner on Tuesday.
Seif al-Din Mustafa, described by Cypriot officials as being mentally disturbed, used a fake suicide belt to hijack the Egyptair flight and forced it to fly to Larnaca.
Egyptian prosecutors say Mr Mustafa should be handed over under a 1996 bilateral extradition treaty.
He has been remanded in custody in Cyprus for eight days.
Possible charges include air piracy, kidnapping and threatening behaviour
