A kidnapping case has been lodged by the family members of the girl at the Sadar Bazaar police station.
A class XII girl was allegedly kidnapped by four unidentified car-borne men from outside her college at Gill Colony on Thursday morning.
Manju, a student of Arya Samaj Inter College and a resident of Hasanpur, was kidnapped from near the college.
Four men grabbed her from behind when she was deboarding an auto-rickshaw and forced her into their van, ASP Sanjay Singh said.
He said Manju left for college along with her three friends. The three girls told police that by the time they called for help, the van had disappeared.
ASP Singh added a few days ago Manju had opposed harassment by a boy who had threatened her of consequences.
Following the incident, Manju's family members and locals in a violent protest at Hasanpur Chowk pelted stones at vehicles injuring a bus driver, Sidhu, and helper Ambresh Kumar.
Police resorted to a lathicharge to disperse the crowd.
