BJP leader Locket Chatterjee was detained by Kolkata police during the '12-hour Bengal bandh' protest, which was organized following police violence against demonstrators at the Nabanna Abhijan rally demanding justice for a doctor allegedly raped and murdered. Chatterjee asserted that increased detentions would only fuel public anger and participation in the protests. The BJP's actions have been met with accusations from the ruling Trinamool Congress, which claims the BJP is instigating chaos and violence, having attacked police during the protests. The unrest resulted in injuries to both protesters and police, with over 200 arrests made throughout the state. In response to the escalating violence, authorities heightened security measures, including requiring bus drivers to wear helmets. The protests have sparked a broader call for the resignation of CM Mamata Banerjee.
