The police are thoroughly investigating the motive behind the participation of the 94 people in the demonstration to unearth whether they are students or intruders, he remarked.

The demonstration, which earlier ran peacefully, took a chaotic turn after the protesters acted in an anarchic manner by breaking through a barbed wire cordon to enter the parliament building.
As the demonstrators forced themselves into the parliament building, the police fired water cannon and teargas to disperse the congregation of rioters.
Gatot remarked that 39 police officers suffered injuries in the incident, while 254 students underwent hospitalization.
