Riot police
In 1999, some of the inmates in the prison went on a rampage against the officials following the death of an inmate named Boxer Vadivelu. They set fire to a room where the assistant warden had taken refuge. Riot police were called in to contain the riots. The police initially used tear gas to quell the rioters, before resorting to live ammunition. In the battle which ensued between the inmates and the riot police, 10 people including a prison official were killed and more than 100 people injured.
