Ram Singh, who is accused of driving the bus on which the 23-year-old student was raped and fatally assaulted by a group of six men in December, hanged himself with his own clothes, said G. Sudhakar, the top police official at Tihar jail.
Singh, along with four other men on trial with him on rape, murder and abduction charges, had been under a suicide watch, another jail official said on condition of anonymity because he was not authorized to speak publicly on the matter. He said the five were being held in separate cells in separate buildings at the jail.
