According to police, the incident took place on Wednesday when the victim was called for a party thrown by her friend Akash at his house in Farsh Bazar where she was held hostage and raped.
"She reached their residence at around 6 pm where Akash's three friends were already present," said the police, adding, "They then allegedly raped her in turns and held her hostage."
Next morning the accused left the victim near her house in Vivek Vihar and escaped from the spot after threatening the victim of dire consequences if she told about the incident to anyone.
Police have arrested three of the four accused who have been identified as Akash, Jatin Goswami and Rohit. The fourth one identified as Raman is still absconding and teams have been constituted to arrest him, said a police officer.
"After registering the case, police started their investigation and arrested three persons from their hideouts on Saturday," the police officer said.
"The college authorities have been informed about the incident and necessary action will be taken against the erring boys," a senior police officer said.
