Four Indian men who were convicted of the gang rape and murder of a student in Delhi in 2012 have been hanged. Akshay Thakur, Vinay Sharma, Pawan Gupta and Mukesh Singh were sentenced to death by a trial court in 2013.

The four were hanged in the capital’s high-security Tihar prison in the first executions in India since 2015. The victim died from her injuries days after being raped by six men on a moving bus. The incident caused outrage and led to new anti-rape laws in India.

The 23-year-old victim who was a physiotherapy student was dubbed Nirbhaya – the fearless one – by the press as she could not be named under Indian law.
