A BSF official said that Commandant Mandal was halting at the Belardappa border outpost - about 60 km south of state capital Agartala - when he noticed some suspected vehicular movement around 1:20 am. The BSF men tried to stop those vehicles, but they refused which led to a chase.
Taking advantage of the dark, a vehicle of the smugglers hit Commandant Mandal, pushing him down a gorge, the official said. Tripura police has detained the vehicle and arrested the driver.
Commandant Mandal was immediately rushed to a local hospital in Agartala where doctors found he had serious head and back injuries. As his condition deteriorated, he was airlifted to a private hospital in Kolkata for better treatment around 11:40 am.
Tripura shares an 856 km border with Bangladesh but despite barbed wire fencing coming up in more than 70 percent of the border, smuggling is rampant.
