KOLKATA — Clashes broke out between police and protesters at different parts of Kolkata and its neighbouring Howrah on Tuesday, as the agitators tried to make their way through barricades to march towards the West Bengal secretariat. The protesters were attempting to reach ‘Nabanna’ to demand the resignation of Chief Minister Mamata Banerjee over the rape-murder of a doctor at RG Kar Medical College and Hospital here. Clashes were reported at MG Road, Hastings Road and areas near the Princep Ghat alongside Santragachi and Howrah Maidan in which some protesters as well as policemen were injured. Police lathicharged and used water cannons and tear gas to disperse protesters who threw stones and bricks at the security forces, and attempted to topple barricades blocking their way to the state secretariat. “Why were we beaten by police? We did not break any law. We are holding a peaceful rally to demand justice for the deceased doctor. The chief minister should take responsibility and resign,” said a woman protester.
