Charu met with an accident March 25. A speeding car, with an allegedly drunk driver at the wheel, rammed into the autorickshaw in which she was travelling with her sister and a friend. The 26-year-old suffered multiple fractures and injuries to her spinal cord in the accident early Sunday and went into a coma.
