The district administration called in the army after imposing the prohibitory orders under section 144 Cr P C from 2:00 pm to contain a second day of protests by weavers who called a 12-hour bandh, official sources said.
Personnel of the Army's Punjab Regiment were patrolling the town along with police and paramilitary forces, the sources said.
The protesters, including weavers and local people, converged on the main market area in the morning and urged the State Bank of India branch to down shutters as a bandh was on, the sources said.
When the protestors refused to disperse and hurled stones at the police which used teargas and rubber bullets, firing was resorted to injuring ten persons, the sources said.
Additional Superintendent of Police Hemanta Das was injured in the stone-throwing.
Of the injured persons, three were taken to Gauhati Medical College Hospital, the sources said.
