Hundreds of activists of the All Assam Minority Students' Union (AAMSU) and All Bodoland Minority Students' Union (ABMSU) gathered at the spot since morning to protest killing of an ABMSU leader at Salakati along Kokrajhar-Chirang border.
They were holding the protest with the body of the leader who was killed by unidentified gunmen outside his pharmacy last night.
Police rushed to the spot to disperse the protestors. When the agitators refused to lift the blockade, police resorted to lathicharge.
The protestors also turned violent and threw stones at a bus on its way from Dhubri to Barpeta.
The driver of the bus and a child sustained mild injuries when they were hit by stones. Both were administered first aid.
The situation in the area is now stable and vehicles have started plying in the NH-31.
