The attack and the national response
On the evening of December 16, 2012, the young woman and a male friend boarded a private bus in New Delhi after seeing a film. Reuters reported that she was gang-raped and fatally assaulted inside the moving vehicle. Her friend was also attacked. Both were later left by the roadside.
The woman was treated first in India and later transferred to a hospital in Singapore, where she died on December 29. Public anger had already grown into large demonstrations, and her death intensified nationwide demands for stronger responses to sexual violence and failures in public safety.
Arrests and prosecution
Six people were arrested in connection with the attack. One, Ram Singh, died in jail in March 2013 before the case against him could reach judgment. Another defendant was under 18 at the time of the crime and was handled through India's juvenile justice system, receiving the maximum detention then available under that framework.
The four remaining adult defendants — Mukesh Singh, Vinay Sharma, Pawan Gupta and Akshay Thakur — were tried in a fast-track court. They were convicted in September 2013 of offenses including rape and murder and were sentenced to death. Their convictions and sentences then moved through a lengthy appeals process.
Appeals and the Supreme Court
India's Supreme Court upheld the death sentences in May 2017. The defendants continued to pursue review petitions, curative petitions and mercy pleas over the following years. Because capital cases require multiple layers of judicial and executive review, the final outcome did not occur immediately after the original convictions.
By early 2020, the principal avenues of appeal and clemency had been exhausted. Courts considered several last-minute applications, including requests to stay the executions. Reuters' timeline documents the sequence from the 2013 convictions through the Supreme Court's rulings and the rejection of mercy petitions.
Executions in March 2020
On March 20, 2020, the four adult men whose death sentences remained in force were hanged at Tihar Jail in New Delhi. Reuters reported that prison officials confirmed the executions at dawn. The event closed the principal adult criminal cases more than seven years after the attack.
The execution itself remains a separate policy question from the defendants' guilt. Capital punishment has supporters and critics in India and internationally. This case file records the sentence imposed and carried out without presenting execution as a universal measure of justice or as a substitute for broader prevention of violence against women.
Changes in law and public policy
The case became a catalyst for renewed scrutiny of India's laws on sexual violence. In 2013, Parliament enacted tougher criminal-law provisions following a government review process. Reporting by Reuters and other major outlets linked the reform debate directly to the public response after the Delhi attack.
The legal changes did not mean that violence against women was solved, and later reporting continued to document serious concerns about enforcement, prevention and victim support. The lasting importance of the case therefore extends beyond the four convictions to the policy debate it intensified.

Current status
The adult criminal prosecutions are fully adjudicated. Four men were convicted, exhausted their principal appellate and mercy remedies, and were executed in March 2020. The juvenile case was handled separately under the law applicable to an offender under 18. The crime remains one of India's most consequential modern criminal cases because of its legal, social and policy impact.
