Mumbai Police has taken "serious cognisance" of a 'Free Kashmir' poster spotted at the Gateway of India last night during protests against Sunday's mob violence at Delhi's Jawaharlal Nehru University. The poster, held by a young woman who later identified herself as Mehak Mirza Prabhu, was among several held aloft by protesters who had gathered at the iconic monument by the sea after a masked mob, armed with iron rods and sledgehammers, attacked JNU students and teachers and left 34 people injured.
