Why is "2012 Delhi gang rape and murder" trending?

Wikipedia Overview

The 2012 Delhi gang rape and murder, commonly known as the Nirbhaya case, involved the gang rape and fatal assault that occurred on 16 December 2012 in Munirka, a neighbourhood in Delhi. The incident took place when Jyoti Singh, a 22-year-old physical therapy intern, was beaten, gang raped, and tortured in a private bus in which she was travelling with her friend, Avnindra Pratap Pandey. There were six others in the bus, including the driver, all of whom raped the woman and beat her friend. She was rushed to Safdarjung Hospital in Delhi for treatment and, as the public outrage mounted, the government had her transferred to Mount Elizabeth Hospital, Singapore eleven days after the assault, where she died from her injuries two days later. The incident generated widespread national and international coverage and was widely condemned, both in India and abroad. Subsequently, public protests against the Government of Delhi and the Government of India for failing to provide adequate security for women took place in New Delhi, where thousands of protesters clashed with security forces. Similar protests took place in major cities throughout the country. Since Indian law does not allow the press to publish a rape victim's name, the victim was widely known as Nirbhaya, meaning "fearless", and her struggle and death became a symbol of women's resistance to rape around the world.
