Curfew was on Sunday relaxed for 12 hours from 8 am in Beltola area of Guwahati -- the scene of a clash between activists of a tribal students union demanding Schedule Tribe status and locals -- which left one dead and at least 240 injured.

Kamrup (Metro) Deputy Commissioner Avinash Joshi said the situation was tense, but gradually returning to normal due to which the curfew had been relaxed during the day time.

On Saturday, largescale violence rocked the area after Adivasi Students Association activists vandalised property, torched vehicles, attacked policemen and injured a magistrate after they were obstructed by the police.

The protestors then attacked private property and shops and set ablaze cars and buses turning the area from Dispur to Bashista into a battleground.

The local people, furious at their property being attacked, retaliated and clashed with the protestors resulting in injuries to both sides.

The army and paramilitary forces were called out to control the situation even as Chief Minister Tarun Gogoi ordered a high level probe into the incident.

Joshi said patrolling continued in the sensitive areas and the district administration was keeping a watch on the situation.

Two hundred injured people have been discharged from the Guwahati Medical College while 40 seriously injured are being treated, hospital sources said.
