A Kolkata court on Saturday declared Sanjay Roy "guilty" of raping and murdering an on-duty doctor at the state-run RG Kar Medical College and Hospital. The Sealdah court, where Roy's trial was held, will declare his sentence on Monday, Anirban Das, the additional district and sessions judge, said.

Roy was found guilty under Sections 64 of the Bharatiya Nyaya Sanhita which governs rape, and Sections 66 and 103 (1) of the Act, which deals with punishments for death and murder.

Section 103 (1) of BNS entails a possible punishment of death or life imprisonment.

The judge stated that Roy was found guilty of sexually assaulting the doctor and strangling her to death and that the CBI had proven all the charges against him.

Das said Roy's statement will be heard at 12:30 pm on Monday, and the sentence will be pronounced thereafter.
