Two lawyers in Cairo and Alexandria have asked for investigations in the death of ex-spy chief Omar Suleiman.

Suleiman, who briefly served as toppled President Hosni Mubarak's vice-president during the 18 days that ousted the regime, died on Thursday in the United States.

His body arrived to Cairo on a special aircraft on Saturday and a military funeral was organized for him.

In Alexandria, a lawyer submitted a request to the general prosecutor asking for the formation of a forensic committee to conduct an autopsy on the former intelligence chief to confirm the reasons behind his death. He also asked for his clothes to be examined and for those responsible to be revealed in case of a suspected murder.

Lawyer Tarek Mahmoud asked for Suleiman's medical records, from the minute he arrived to the Cleveland hospital in Ohio until his death, to be restudied.

In Cairo, lawyer Essam Kandil also submitted a request to the general prosecutor asking for an investigation in the same death. He asked to hear the testimonies of Mubarak and writer Mohamed Hassanein Heikal.
