New Delhi, Aug 24 (IANS): Delhi Chief Minister Arvind Kejriwal on Monday said the alleged abuse of Delhi University student Jasleen Kaur in Tilak Nagar by a youth on a motorcycle was "unacceptable".

"Congratulate @jasleenkaur89 for her bravery. Girls of Delhi should follow her and speak up against such unacceptable acts," Kejriwal said in a tweet on Monday.

Police said Jasleen Kaur was abused at a traffic signal in Tilak Nagar here around 8 p.m. on Sunday.

"A man made obscene comments at me today (Sunday) at around 8 p.m. near Aggarwal, Tilak Nagar. He was on a silver Royal Enfield, vehicle number DL 4S CE 3623. When I told him I am clicking his picture and I'm going to file a complaint against him, he responded by posing for a picture and said, "Jo kar sakti hai kar le. Complaint karke dikha, fir dekhiyo kya karta hun main (Do whatever you like. Complain and see what I do then)," Jasleen said in her Facebook post.

A case of sexual harassment and criminal intimidation was registered against the biker and he was arrested, police said on Monday.
