Speaking outside the court, the victim’s mother said: ‘I am very satisfied. Today I am happy.’
Her father said: ‘It’s not just a victory for my family, it’s a victory for each and every woman in our country.’
The crime sparked large-scale protests and led thousands of women across India to break their silence over sexual violence that often goes unreported.
It also shone a spotlight on what women’s groups call a rape epidemic in the country.
In 2015, police registered more than 34,000 rape complaints and 84,000 women filed sexual harassment cases, according to the National Crime Records Bureau.

A.P. Singh, a lawyer representing three of the condemned men, said justice had not been done. He vowed to file a review petition to the chief justice of the Supreme Court.
