An Indian court has sentenced a police volunteer to life in prison after finding him guilty in the rape and killing of a trainee doctor last year.

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

An Indian court handed down a life sentence on Monday to a police volunteer convicted of the rape and murder of a junior doctor at a hospital in the eastern city of Kolkata, rejecting demands for the death penalty saying it was not a rare crime.
