The girl was forcibly taken away by the youths when she had gone out to buy biscuits for her mother, they said.
The duo took the girl near a mall at Rajarhat where she stumbled, fell down and became unconscious. This drew attention of the locals whose presence forced them to flee, they said.
The locals then escorted the girl to her mother.
Later the girl lodged a complaint with the Bhawanipore police station about the incident. Police said the girl had an affair with one of the youths earlier.
