One-hundred and eighteen "troublemakers" were arrested in Cairo's recent clashes where 99 people were injured, the Interior Ministry said on Wednesday.

Legal measures are currently being taken against the defendants who were referred to the general prosecution, a statement by the ministry has confirmed.

A delegation from Egypt's Criminal Investigation Department is currently studying the defendants' incentives and their agitators.

Confrontations between protesters and security forces broke out in Tahrir and streets leading to it on Monday evening on the anniversary of last November's "Mohamed Mahmoud events" where over 40 people were killed.

The confrontations, that dragged on until the early hours of Tuesday, picked up last night, increasing the number of injuries to 99; seven police officers, 37 conscripts and 55 civilians.

Cairo prosecution has so far detained 11 defendants for four days pending investigation, released 13 and handed over nine minors to their families.

It accused the defendants of "gathering", a crime frowned upon under Mubarak's rule, attacking the police and disturbing public order.
