Several Muslim Brotherhood figures were slammed Saturday with three to 15 year prison sentences on charges of torturing an opponent protester during the 18-day Tahrir Square sit-in that led to the ouster of Hosni Mubarak in 2011.

Brotherhood leading member Mohamed El-Beltagy, Islamic preacher Safwat Hegazy in addition to Brotherhood member Hazem Farouk and Al-Jazeera's Ahmed Mansour were handed 15-year sentences. Brotherhood members and loyalists Omar Zaky, Mohsen Rady, Osama Yassin and Judge Mahmoud El-Khodeiry were given three-year sentences.

Lawyer Osama Kamal had filed a complaint in 2011 accusing the defendants of beating and torturing him in Tahrir Square after claiming he was a police officer when he failed to show them an identity card.

A video earlier circulated on social media, and picked up by satellite channels, showed the alleged torture.

Thousands of Brotherhood members and loyalists of deposed president Mohamed Morsi were rounded up and arrested over the past year. They face numerous charges, including inciting and committing violence against their opponents.
