Tear gas used against protesters in India over rape and murder of trainee doctor

Protests have erupted in India's West Bengal state following the rape and murder of a 31-year-old doctor at a hospital in Calcutta on August 9. Demonstrators, including university students, are marching to demand justice and the resignation of Chief Minister Mamata Banerjee, citing a botched investigation. Police have responded with tear gas, water cannons, and batons to disperse the crowds, with some protesters breaking through barricades set up by security forces. The incident has sparked nationwide outrage over violence against women, with the arrested suspect being a hospital volunteer.
