SHARM EL-SHEIKH, Egypt (CNN) -- Former Egyptian President Hosni Mubarak, now under investigation in connection with the deaths of protesters, was transferred from a hospital here to a military facility in Cairo, Egyptian Supreme Armed Forces spokesman Major Mohamed Askar told CNN on Saturday.

Justice Minister Mohamed Abdel Aziz had said that when the former leader's health improves, he will be imprisoned.
Hospital officials would not confirm that Mubarak had left, saying he hadn't moved from a heavily guarded section of the facility.
The country's attorney general decided to make the transfer and put the former longtime ruler under the surveillance of guards, according to Nile TV.
Despite his health issues, Mubarak has been questioned and been under investigation by the Egyptian prosecutor-general's office since Tuesday.
He is being investigated in connection with the deaths of hundreds of activists during the recent uprising that led to his departure from office February 11. He is also under investigation for allegations of corruption and misuse of state funds.
Mubarak has been treated at the hospital since Tuesday for heart palpitations and blood pressure problems and is listed in stable condition, officials said.
He and his sons were taken into 15-day detainment Tuesday, according to a Justice Ministry spokesman. His sons are in custody in Cairo.
Aziz also said Mubarak's wife, Suzanne, will be questioned by the ministry's Office of Illicit Profiteering.
