New Delhi (CNN) Four men have been issued with death warrants for the brutal gang rape of a 23-year-old physiotherapy student in New Delhi more than seven years ago.

The men were on Tuesday ordered to hang later this month for gang-raping the woman on a bus in 2012. She died two weeks later as a result of her injuries.

The hanging is scheduled for 7 a.m. on January 22 at Tihar Jail in India's capital, the court announced via video conference.

While the four men have exhausted the review process, they can still file a petition against the sentencing within the next 14 days, and if successful that would go to the country's Supreme Court.
