A suspect detained in connection with the alleged rape of a Pune IT professional at her home was her friend and not a stranger who gained entry by posing as a courier delivery agent, police said on Friday, casting doubt on her version of the events.

It was the woman herself who took a selfie with him and typed a threatening message in her phone, police commissioner Amitesh Kumar said.

"They know each other for a couple of years and belong to the same community," he said.
