The family of an Indian teenager from India's lowest Hindu social caste said he died on Monday after being beaten with a stick by a school teacher for making a spelling error during class, and police said they were investigating. Relatives of Nikhit Kumar, 15, said he was declared dead by doctors in the Auriya district of northern Uttar Pradesh state 19 days after the corporal punishment was meted out by his teacher on a private school campus. "At first my nephew was beaten brutally by the teacher and then abused as we are Dalits," said Rishi Kumar, an uncle of the boy.
