Curfew was imposed on Monday in Mahendraganj area in South West Garo Hills district after an angry mob stormed into Mahendraganj police station and vandalized government property.
The mob attacked the police vehicles in protest against an alleged firing by police on a mentally ill person, who ran away after snatching an INSAS rifle from a police constable on Sunday night.
The person, identified as Ahidul Islam, had allegedly snatched the rifle from police constable Pini Sangma on Sunday at around 8.30 pm.
