GIZA - Security forces have arrested Friday two male suspects in connection with the killing of a policeman and injuring two others during an armed attack on a police prison van in Giza late Tuesday, the Interior Ministry said. The police arrested the men who were hiding in the small town of el-Saaf after they had ambushed the prison car near Ayyat Village in which one soldier was killed, and two others injured, the Ministry said in a statement carried by Egypt's official Middle East News Agency (MENA). "The attack was apparently in revenge for the jailing of Abdul Aziz Hamza Abdul Aziz, a drug baron, who was arrested on many criminal charges and being transferred to prison to serve a five-year term," the statement said. The police identified the arrested men as Hamza Abdul Aziz Abu Seliem, a 45-year-old fisherman, and Sanaad Hamza Abdul Aziz Abu Seliem, who are suspected of being behind the ambush in which the vehicle was raked with bullets, it said. Policeman Mohamed Khalifa was shot dead at scene. His colleagues Warrant Sergeant Mansour Mohamed and Sergeant Sayyed Gebril were hospitalised with grave gunshot wounds in the leg. However, Abdul Aziz could not escape from the car after the two men, armed with automatic rifles, attacked the van shortly after it left the Giza Criminal Court, the statement said. Hamza and Sanaad will be referred to Giza prosecutors for interrogation, it added.
