Egyptian authorities are trying to shut down Egypt's main NGO treating torture victims, many of whom say they were abused by the police or security forces.

Aida Seif el-Dawla, one of the founders of the Nadeem Center, says government officials came Tuesday to its offices in downtown Cairo and ordered the premises closed while refusing to show any official documentation. Police originally attempted to shut down the center in February.

She says the officials, from the Health Ministry and local police, were aggressive and said that the center did not have the right to see the orders.

Seif el-Dawla and another doctor refused to leave the office, and the officials left saying they would inform the Interior Ministry, in charge of police, of the move.
