Zakareya Azmy, the former chief of staff to deposed President Hosni Mubarak, was sent back to Tora Prison on Monday after testifying against Mubarak in trial.
The former president is facing profiteering charges.
Azmy testified that Mubarak habitually seized donations granted to the Bibliotheca Alexandrina and saved them in his personal account at the Ahly Bank.
The donations largely came from foreign businesspeople, and Mubarak was the only one with access to the money, Azmy said.
