India, Aug. 9 -- The mother of the deceased RG Kar Medical College student, who was raped and murdered last year in Kolkata, has accused West Bengal chief minister Mamata Banerjee's police force of manhandling her during a protest on Saturday.

She alleged that she was roughed up by women police personnel while on her way to join a march to West Bengal state secretariat 'Nabanna', called to mark one year of the rape and murder of her daughter in a state-run hospital.

The woman claimed that in the scuffle, her 'shankha' (traditional conch shell bangle) was broken and she sustained a head injury.

"Why are they stopping us like this? All we want is to reach Nabanna and seek justice for my daughter," she said.
