CAIRO – An Egyptian prosecutor placed a new detention order on Hosni Mubarak on Saturday after the ousted ex-president was questioned over valuable gifts he allegedly received from the country's top newspaper as a show of loyalty while he was in power, a security official said.

The public funds prosecutor ordered Mubarak to be held for 15 days pending investigation, the official said. The former president is already serving a life sentence after being convicted for failing to stop killings of protesters during the 2011 uprising that overthrew him. But he is scheduled to hear a ruling on his appeal on Sunday, and the detention order could prevent him from walking free pending retrial were the appellate court to rule in his favor.

He was moved to a Cairo military hospital last month after slipping inside a prison bathroom and injuring himself.
