NEW DELHI (CNN)—One of the men who is accused of gang raping and fatally beating a woman on a bus in India has been found dead.
Police say Ram Singh hanged himself but his family says the man was murdered.
Authorities say Singh was the driver of the bus where several men brutally raped a 23-year-old woman in December.
The woman later died of injuries she suffered during the attack.
Singh and four other men were charged with murder, rape and kidnapping.
The rape led to protests for stricter laws on sexual assault and changes in cultural attitudes toward women.
