Large groups of passers-by joined the students who were chanting such slogans as "death to dictatorship" and "freedom, freedom," demanding the overthrow of the clerical regime.
The regime's suppressive forces, including the Revolutionary Guards, State Security Force and special anti-riot forces, attacked the crowd with batons, knuckle-dusters and chains and began to beat them up.
In the course of the clashes, which continued until 6:00 p.m., more than 100 teenagers and students were arrested and taken to an unknown location.
