At least four people died and 15 were critically injured after a vehicle fall in the gorge in the Lakri Dokan area on the Amarpur – Nutan Bazar Road.

The incident occurred on Friday when some BJP workers were travelling through the Amarpur – Nutan Bazar Road after attending a public meeting of Tripura chief minister Biplab Kumar Deb in Nutan Bazar Malbasa Autonomous District Council (ADC) constituency in South Tripura district.
The BJP workers had been travelling by a truck, which turned turtle after the driver of the vehicle lost control while taking a U-turn.
The chief minister had attended a roadshow and a public meeting in support of BJP candidate Atindra Riang of Nutan Bazar Malbasa ADC constituency on Friday ahead of the Tripura Tribal Areas Autonomous District Council (TTAADC) elections.
