The incident took place around 4.30 PM on Thursday when the woman, who is pursuing PhD at the Department of Hindi in DU, was sitting outside the canteen which is located inside the Arts Faculty and spotted the men consuming alcohol openly.
"Suddenly, they approached the woman, trying to strike a conversation. When she did not show any interest, they collected some rain water in a glass and spilled it on her. Whenshe objected, they started misbehaving with her," a police official said.
The group then turned vulgar and started abusing her. The woman called up the police control room but by the time the officers arrived, the men fled the scene in a car, whose number the complainant had noted, the official said.
The police later registered a case under IPC Section 509 (Word, gesture or act intended to insult the modesty of a woman) in connection with the matter, the official said.
