The leg and intestines of Bradford restaurant owner Nissar Ahmed, 34, were found a few days ago by an off-duty policewoman walking her dog in Dewsbury, West Yorkshire.

Officers said on Thursday that they had found more remains at Lepton near Huddersfield and Holme near HolmFirth.

Det. Sup. Graham Sunderland: Seeking information

They also believe that other body parts have been hidden at Copley near Huddersfield, and at West Vale and Elland near Halifax, bringing the total number of sites to six.

Detectives said the searches would be carried out on Friday and that forensic tests were being conducted to determine whether the most recent remains found also belonged to Mr Ahmed.

Mr Ahmed, from the West Bowling area of Bradford, was identified by his family by a circular scar just above the ankle.

A white bin liner containing the leg from a pair of denim jeans was found near the place where Mr Ahmed's leg was discovered.

Police said the remains had been thrown there with no attempt made to conceal them.
