Arshdeep Kaur and her mother Shinder, were travelling from their home in Punjab, northern India, to visit relatives when a group of about half a dozen men began harassing them.

Mrs Kaur, 38, daughter Arshdeep, 14, and son Akashdeep Singh, had taken the bus from their home village to visit Mrs Kaur's parents, Tribune India reports. Shortly after boarding the bus, a group of men had surrounded mother and daughter and tried to grab both of them.

After fighting off her attackers, Mrs Kaur ran through the bus to tell the driver to stop the bus, but according to her testimony, he started driving faster. The incident took place on a near-empty bus near Moga, some 50 miles from the Pakistani border, in Punjab province . Vital issue: Officials recently banned a documentary about the 2012 gang rape and murder of an 23-year-old student in Delhi (stock image) The assault continued until the bus slowed down and mother and daughter could break free, however as they attempted to get off the bus, Mrs Kaur says they were pushed. Arshdeep and Mrs Kaur both suffered serious injuries, and the 14-year-old later died in hospital. 'No one helped. They first pushed my daughter off the bus, then me,' Mrs Kaur told NDTV from her hospital bed today. Shortly after the pair had been pushed off, the bus stopped by the roadside and the alleged perpetrators, including the conductor, cleaner and driver fled the scene. The three could later be apprehended and police have launched an investigation into the incident. There has a heightened sensitivity to the issue of sexual assault in India in recent weeks after officials banned a documentary about the 2012 gang rape and murder of an Indian student in Delhi. Officials said the documentary, called India's Daughter, would cause further disorder if it was shown, following a number of protests and incidents of vigilante justice in the country. The documentary explained the brutal rape and murder of 23-year-old student Jyoti Singh, who was attacked on a bus when she returned home from the cinema. One of the six men convicted of the attack, bus driver Mukesh Singh, was interviewed in prison and told researchers that had Jyoti not fought back she would not have been killed. Her death led to protests throughout India and outraged the world. Jyoti Singh Pandey, a physiotherapy student, was gang raped as she travelled on a bus. The 23-year-old suffered in hospital for 13 days from her injuries before she died. Vinay Sharma, 20, Akshay Thakur, 28, Pawan Gupta, 19, and Mukesh Singh, 26, were all sentenced to death for her rape. Ram Singh, co-accused and widely considered the leader of the group, was found dead in his cell. A minor also found guilty was sentenced to three years in a reformatory institution. Her death sparked angry protests in India and internationally about misogyny in the country. The attention forced judges to prioritise the case and the lawyer's association in Saket reportedly refused to defend the perpetrators.
