Baksa, in lower Assam and under Bodoland Territorial Autonomous District (BTAD), was one of the districts affected in the recent clashes between Bodos and minorities that claimed 77 lives so far.
In an incident related to these clashes, a car was set ablaze at Gandhibari in Baksa district last night and its driver, Sahidul Hussain, has been missing since then.
The car was returning from Baksa to Rangiya in neighbouring Kamrup (Rural) district.
After the news reached Rangiya, angry local residents blocked NH-31 at Udiana Chowk under Rangiya police station since early this morning to protest against the incident, sources said today.
During the blockade, some people set ablaze a bus going towards Guwahati at Bhatkuchi and a wooden bridge at Kekahati, both under Rangiya police station.
Police fired in the air to disperse the protestors who scattered for some time only to return again and tension prevails in the area, the sources said.
Senior police and civil officials have rushed to the spot, sources added.
