Al Jazeera's correspondent in Cairo speaks of interrogation, intimidation and beatings during military detention.
"....."It was just the mere fact that I was a journalist who was trying to go into Liberation Square that seemed to be enough for them to take me for further questioning."
Mohyeldin describes how he was taken to a separate holding area, where he was handcuffed with plastic strips, had his equipment taken off him and was interrogated.
At least two other journalists were already present at the holding area.
Other detainees appeared to have been severely beaten, intimidated and at least one person broke down in tears under the pressure.
While foreign journalists were released fairly quickly, Mohyeldin and a Reuters cameraman of Palestinian descent were held for an extended period.
All of the detainees who were released were told to sign a document that said that they would not attempt to return to Tahrir Square without permission from the military."
