The woman, hailing from Darjeeling, and working in a call centre of a multinational company here, was on her way to office last night when the incident took place.
"The two youths, who were known to the victim, approached her and tried to talk to her. When she refused, they harassed her and touched her inappropriately," said a police official.
Later, the woman approached the police and an FIR was registered at Vasant Vihar Police Station.
Both the youths have been identified on the basis of the victim's statement and efforts are on to nab them, the official said.
