A minister in the government of Mohamed Morsi has been convicted of stealing state television trucks during the Muslim Brotherhood-led Rabaa sit-in in July-August 2013
Former information minister Salah Abdel-Maksoud, who was tried in absentia, and Amr Darwish, the former head of radio engineering at the state broadcaster, were sentenced to ten years in jail.
They were also fined LE3 million.
Abdel-Maksoud, a leading member of the Brotherhood, was also a longtime member of journalists syndicate board of directors.
The state television broadcasting trucks were used to transmit live footage of Islamist speeches during the Rabaa sit-in, which called for the reinstatement of Mohamed Morsi.
The sit-in was dispersed on 14 August 2013, leaving 703 dead, according to a government-appointed committee.
The Brotherhood was officially declared a terrorist organisation in December 2013. Membership of the group, or support for its activities, are now criminal offences.
Thousands of Islamists and suspected Morsi loyalists have been arrested since his ouster.
Morsi himself is facing a number of trials on different charges, some of which include espionage and jail break.
Earlier this month, Giza criminal court sentenced 188 defendants to death for a violent attack on a police station after last year's ouster of Morsi, which left 11 police personnel and two civilians dead.
