Young boys armed with knives and lathis terrorized the streets. Police fired several tear gas shells and resorted to charging with their lathis. The Provincial Armed Constabulary usually carries only "lathis". The "sainiks" are training in using lathis. In the beginning the students were trained with lathis and wooden swords. Water cannon and Lathis were used to disperse the gathering. This provoked criticism, as several video clips showed officers carrying lathis. Some Indian police forces use lathis around long, but in other places lathis are shorter. Depending on the assignment, the Provincial Armed Constabulary may only carry lathis.
