A woman, who was allegedly set on fire by a person after she apparently did not reciprocate to his overtures in Jharkhand's Dumka district, succumbed to her burn injuries in the early hours on Sunday, police said. The 19-year-old woman, a student of Class 12, had been first admitted to Phulo Jhano Medical College and Hospital in Dumka in critical condition with 90 per cent burns. Later, she was referred to Ranchi's Rajendra Institute of Medical Science (RIMS) for better treatment, the police said.
