A manager at the Cairo Institute for Human Rights Studies said that investigators from the Ministry of Social Solidarity visited its offices yesterday to look into the legality of its activities, showing them only a photocopy of a warrant and not leaving them with any document.
The group says the move is in retaliation for the May 28 speech its director, Bahey Eldin Hassan, gave to the parliament's Human Rights Committee, where he criticised human rights abuses in Egypt.
"They are showing zero tolerance for any sort of criticism," he said, adding that the investigators wanted to see all the group's files and documentation but that the office refused, given that an original warrant was not shown.
Rights groups and activists allege widespread abuses since the ouster of Egypt's Islamist president, Mohammed Morsi, in 2013, and say torture is being used to punish detainees or extract confessions.
Last week, prominent rights activist Mohammed Lotfy, who was due to speak before Germany's parliament during a visit by President Abdel-Fattah el-Sissi, was banned from travelling at Cairo International Airport and had his passport confiscated.
