CAIRO - The Chairman of the Egyptian Organisation for Human Rights (EOHR) Hafez Abou Se'da said that the organisation has assigned a fact-finding committee to investigate the Tahrir events, the official Middle East News Agency reported on Thursday. Public-police clashes led by some people, who alleged that they are families of people killed in the January 25 revolution, broke out late on Tuesday in Agouza, a district of Giza. The angry families moved on to Tahrir square, making chaos and prompting the Police to interfere. Police fired teargas at the angry people that threw stones in the direction of the police force in riot gear and shields. According to the Egyptian Ministry of Health more than one thousand from both sides were injured. Abou Se'da said that confidence between the police and the public has not been fully restored and so any disturbance would have an adverse effect on Egypt. Some political observers said that tension had erupted following the verdict of dissolving the local councils. They also hold some of the loyal men of the ousted Mubarak's regime responsible for the repeated clashes. Se'da called on the Ministry of Interior to maintain self control and to try to restore safety to Egyptian streets. Se'da referred to mounting public frustration over what they see as slow-pace judiciary in cases where some officers are being tried for killing protesters in the January 25 revolution. Meanwhile, earlier in the day an Egyptian court postponed issuing a verdict in a high profile police brutality case until September. A large security presence had been deployed outside the courthouse in the Mediterranean city of Alexandria where dozens of activists had gathered to hear the ruling in the trial of two police officers accused of beating to death 28-year-old Khaled Saeed last year.
