The Central Bureau of Investigation (CBI) will file an appeal before the Calcutta High Court (HC), seeking death sentence for Sanjoy Roy, who was sentenced to "life imprisonment until death" by a Sealdah court in the Kolkata rape-murder case,

An Indian court on Monday sentenced a police volunteer to life imprisonment for the rape and murder of an on-duty doctor last year – a crime that sparked nationwide protests. Sanjay Roy, 33, plans to appeal the judgment in a higher court.

An Indian court awarded the life sentence on Monday to a police volunteer convicted of the rape and murder of a junior doctor at the hospital where she worked in the eastern city of Kolkata. The woman's body was found in a classroom at the state-run R G Kar Medical College and Hospital on Aug.

The police had sought the death penalty in a horrific but familiar crime. Its handling by the local authorities had outraged the nation.
