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.
The mob then forcibly took out goods from the shops selling clothes labelled 'Assam silk' and made bonfires of them on the roads claiming they were not genuine pure Assamese golden Muga silk and white Paat silk unique to the state.
When the protestors refused to disperse and hurled stones at the police which used teargas and rubber bullets, 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.
