The Supreme Court will hear an appeal by city police challenging the lenient sentence imposed by the Delhi High Court to Sanjeev Nanda, convicted for mowing down six persons with his speeding BMW car in a drunken state 10 years ago.

The city police contended that Nanda, a grandson of former navy chief S M Nanda, should be convicted under the stringent provision of Section 304 (Part II), which is culpable homicide not amounting to murder.
