president Hosni Mubarak and his two sons have been placed in detention for 15 days as part of an inquiry into the use of force against protesters, prosecutors said on Wednesday. A statement on the public prosecutor's Facebook page said chief prosecutor Abdel Maguid Mahmud authorized the detentions “as part of an inquiry into the use of force against protesters during the unrest in January and February”. Security officials said Mubarak was placed under detention in a hospital in the Red Sea resort of Sharm el-Sheikh, where he reportedly suffered a heart attack Tuesday during questioning. Officials said he would be transferred to the International Medical Center on the outskirts of Cairo where he will be hospitalized in police custody. The official MENA news agency had reported that security was beefed up in his Sharm El-Sheikh hospital room and he would be taken to a cell once his condition allowed his transfer. His two sons Gamal and Alaa arrived mid-morning at Tora prison complex in Cairo, home to other fallen officials and some of the country's most notorious political prisoners. MENA reported that Gamal, once seen as his father's anointed heir, and his elder brother were handed white prison uniforms, blankets and mattresses after they surrendered their cell phones. They are accused of incitement to fire at demonstrators during a popular uprising which forced Mubarak to stepp down. Nearly 800 people died during the uprising. Earlier, state television said the brothers were being detained for 15 days “for the needs of the inquiry” and had first been interrogated in Sharm El-Sheikh. The inquiry had been ordered as part of a sweeping probe into corruption and abuse. The Mubaraks were to be asked about chargess that they were “connected to the crimes of assault against protesters, leading to deaths and injuries”, the official MENA news agency said.
