A video of two sisters assaulting three men, who were allegedly sexually harassing them while on a moving bus in India, has gone viral on social media.

Police are reporting that the men have been arrested and charged with assault.

The incident, took place in the northern state of Haryana last Friday, was recorded by a passenger on a mobile phone.

The two students seen in the video were on their way home.

The younger sister described to BBC Hindi how the three men "threatened us and abused us".

"The men started to abuse me and touch me. I told them 'if you touch me again, you'll get beaten up'. They called a friend on the phone and told him to 'come over because we have to beat up some girls'.”

She added that they decided to take on the attackers when other passengers did not come to their help.

"No one came forward in the bus to help us. So we took out our belts in self-defence [and hit the men]. If only the other passengers had helped us, we would not have needed to retaliate in this way," she said.

The sisters said the men pushed them out of the bus when it stopped some time later and attempted to assault them again.

They retaliated by throwing a brick at the men who then fled.

Violence against Indian women has been in the spotlight since a student was gang raped and murdered on a bus in the capital, Delhi, in December 2012.
