Egyptian security services have arrested an opposition figure shortly after he flew in from a trip to Britain, airport officials said. They said Musa Mustafa Musa, deputy head of the newly founded al-Ghad party, was detained on Wednesday on a warrant issued by the attorney-general in connection with an investigation of the party's leader, Ayman al-Nur. An Egyptian state security judge on January 31 ordered the detention of Nur for 45 days pending a fraud investigation. Aljazeera reports that the arrest was ostensibly related to a case of forgery of which the detained al-Nur was a beneficiary.
