A young woman from Japan was groped, harassed and manhandled by a group of men in Delhi during Holi celebrations on Wednesday. A video of the incident, which is viral on social media, has sparked outrage and calls for tough action.
In the video, the men are seen grabbing her and smearing colours on her amid chants of "Holi Hai."
A boy is also seen smashing an egg on her head.
The woman says "bye, bye" in an attempt to escape the group as she is pushed around.
She slaps a man who tries to hold her before she finally manages to step away, the video shows.
By the end of her ordeal, the woman was drenched and almost unrecognizable.
"Prima-facie, on the basis of landmark seen in the video, it seems that the video pertains to Paharganj, however, it is being verified on ground whether any such incident took place in that area or the video is old one," said Delhi police.
No complaint or call relating to any kind of misbehaviour with any foreigner has been received in the Paharganj police station, it said.
"An e-mail has been sent to Japanese embassy requesting for help in establishing the identity of the girl or any other detail about the incident," the police said in a statement.
The police are trying to establish the identity to the boys seen in the video through beat/division officers and local intelligence and said action will be taken once the details are verified.
Many have flagged the video to the Delhi Police and the National Commission for Women for action.
BJP leader Khushboo Sundar, who is a member of the National Commission for Women, tweeted: "Sickening. The woman has to send a notice to NCW".
The NCW is trying to establish contact with the woman as well.
Holi, the annual festival of colours, was celebrated in Delhi and parts of northern India on Wednesday. Many states celebrated Holi the day before.
