New Delhi: The Delhi Police has moved the Delhi High Court seeking enhancement of life term to death for 2008 Batla House encounter case convict Shahzad Ahmed for killing a decorated police officer on duty.

A bench of Justices P K Bhasin and V P Vaish issued notice to Shahzad on the appeal of the prosecution seeking death penalty for him.

Advocate Rajesh Mahajan, who has filed the appeal on behalf of Delhi government, said, "We have sought enhancement of the punishment awarded to Shahzad on the ground that the case is rarest of rare as it involves the killing of a police officer during discharge of his duty."

The high court has sought response from the convict by January 16.

Shahzad, 25, was awarded life imprisonment on July 30 by a sessions court for killing the police officer in the September 19, 2008 encounter when a team of Delhi Police Special Cell raided the Batla House flat in Jamia Nagar on a tip-off that terrorists involved in the September 13, 2008 serial blasts in the city were holed up there.
