The parents of the doctor who was raped and murdered at the RG Kar hospital moved the Calcutta HC on Thursday, seeking a fresh investigation. Justice Tirthankar Ghosh asked their lawyer to add the CBI, which is probing the case, as a party in the petition and mention the matter again before the court on Monday.

The on-duty postgraduate trainee doctor’s body was found in the seminar room of the RG Kar Medical College and Hospital on August 9.
