Besides vandalising and torching the place of worship at Wangkhei, known as Panthou Shanglen, the mob also set on fire 13 vehicles, following a dispute between its authority and locals, police said.
The officer in charge of Porompat police station and three persons, including a child were injured in the incident, police said.
A fire brigade official told PTI it took about two hours to control the fire but the damage could not be calculated immediately.
