A 17-year-old girl was allegedly raped and strangled to death by an unidentified person at her house in Dhayari area off Sinhagad Road here, police said.
The incident took place on Thursday, they said.
Talking to PTI, Joint Commissioner of Police Shivaji Bodkhe said the deceased lived in a tenement with her family.
"The victim's brother came home from school in the afternoon on Thursday and found his sister lying unconscious. He immediately informed his parents, who were away from home at that time. They work as labourers," he said.
Her father then called their neighbour, who is a nurse and asked her to check what has happened.
