Ten Central Security recruits and officers were injured in clashes with football fans on Thursday evening during a match between Zamalek and Wadi Degla at Cairo Stadium that ended in a tie.
According to Major General Salah al-Sherbiny, assistant interior minister for the Central Security Forces, initial reports said that eight recruits and two officers sustained fractures and bruises from the fighting.
Ultras, a network of football supporters whose disenchantment with police has put them on the front line of the revolution, chanted before the clashes, "Tomorrow in Tahrir: revolution and change."
The scuffle broke out in the third-tier seats as 400 fans protested against police, as well as referees, who they said were biased against Zamalek, according to security sources.
Security officials asked Zamalek Club Director Ibrahim Hassan to calm the public, but a large number of fans refused to listen to him and set seats on fire.
The Central Security Forces eventually emptied the stadium and arrested some spectators, after which the military inspected the damage.
