The women defied night curfew at many places in Imphal East and West districts of Manipur.
The protesters were demanding resignation of Chief Minister Ibobi Singh on moral grounds over the killing of a youth in an alleged fake encounter on July 23.
Women, carrying torch lights, turned up in large numbers at Chingamakha, Tidim Road and other areas around 8.45 pm on Saturday night.
Police tired to prevent them but were forced to burst teargas shells when the protestors went on with their agitation. Sources said that no casualty was reported.
