A post mortem examination has confirmed that Bikram Atwal, who was found dead in the lock up of the Andheri police station on Friday, died by suicide.

Atwal, a sweeper by profession, was arrested after he allegedly sexually assaulted and murdered a 23-year-old air hostess in Marol on September 3. He was found dead on Friday morning when he was due to be produced in court. He was believed to have hanged himself using his trousers in the bathroom.
