After she regained consciousness, she returned home and narrated her ordeal, following which the police were informed.
She was taken to a hospital and was later discharged. She is currently undergoing counselling, police said.
The police are questioning the hotel employees to identify the accused.
According to the police, the girl stays with her mother and two siblings in a rented accommodation. Her father had died sometime back.
