BJP also hit out at the Tarun Gogoi-led Congress government in Assam for not initiating prompt action in the incident, resulting in a few of the accused still remaining absconding.
"It is a shameful incident...The BJP demands that immediate action be taken and the perpetrators of that violence go through a speedy trial and punishment is given to them," BJP spokesperson Nirmala Sitharaman said.
Taking the opportunity to hit out at the general law and order situation in the country, she said crime against women was increasing everywhere.
"Not just in Assam. Everywhere we are repeatedly coming across situations where women are being beaten up in public by unlawful elements and those people are not very quickly brought to justice," she said.
A total of four persons have been arrested in connection with the incident in front of a bar on the Guwahati-Shillong Road on Monday night, which led to a public outcry after a video of the shocking incident was uploaded on video-sharing website YouTube.
Police action was initiated after the victim's mother lodged a complaint. All the accused have been booked under various sections of the Indian Penal Code (IPC).
