Imphal/IBNS: A mob vandalised and set on fire the venue of Manipur Chief Minister N Biren Singh's programme scheduled for Thursday in Churachandpur district.

The police said the situation is tense and they have increased security in the district, some 63 km from state capital Imphal.

Biren is scheduled to inaugurate a gym and sports facility in the district.

Visuals of the incident show huge crowds breaking chairs and damaging property inside a hall where Singh is scheduled to visit on Friday.

They also set on fire sports equipment and the grounds where the event will be held.

The authorities have not yet confirmed whether the programme has been cancelled.

The protest was allegedly led by the Indigenous Tribal Leaders' Forum, which has been objecting to the BJP government's survey of reserved and protected forests and similar areas like wetlands.
