Six women sustained injuries when the police fired tear gas shells and smoke bombs at a marketplace here to disperse protesters, who had enforced a road blockade demanding withdrawal of the citizenship bill, according to a vendors' association at the market.
There was, however, no immediate official confirmation about the incident.
Shantidevi, the president of an association of women vendors at Khwairamband market here, claimed that the police on Sunday used force on the agitators, who had been protesting peacefully.
The women vendors at the market here had put up posters and banners and set up tents, blocking roads, to press for their demand, she said.
Prohibitory orders under section 144 of CrPc have been imposed in the area in the wake of agitations against the contentious bill.
Shantidevi said the police tried to pull down the tents and tear apart the posters and banners that sought the unconditional revocation of the bill.
