A human rights organization on Tuesday demanded the immediate release of protesters detained Monday after military and police dispersed the sit-in at Tahrir Square.
In a statement, the Arab Network for Human Rights Information (ANHRI) expressed its shock about the move and the arrests of 111 people.
"The return of violence and repression after a revolution against a dictatorial regime is extremely regrettable," ANHRI said.
The organization said statements from the ruling Supreme Council of the Armed Forces (SCAF) "often betray" revolutionaries and describe them as thugs, vandals and agitators who want to divide people and the army.
This is "unacceptable from members of a council that declared in its first statement that it's the protector of the revolution," ANHRI said.
The organization urged SCAF to stop accusing revolutionary groups of treason.
It also demanded an immediate release for protesters tried before military courts and called for investigating alleged human rights abuses by army officers.
On Monday, SCAF member Ismail Etman said detainees arrested at Tahrir Square will be interrogated by the Public Prosecution.
But activist Mona Seif told Al-Masry Al-Youm that the detainees spent the night in the Hikestep military camp in Cairo.
Seif said human rights lawyers on Tuesday went to the military prosecution headquarters to wait for either the arrival of detainees or interrogators.
