Forensic tests could prove vital in the inquiry into a mystery body found in Ravensthorpe.

A post-mortem examination was due to take place last night and police are awaiting results.

The medical results are expected to indicate whether or not a crime has been committed or if the death was due to natural causes.

Police have also made an extensive search of wooded and grassed areas close to the Calder and Hebble Navigation Canal in Ravensthorpe looking for possible clues to the identity of the victim.

The site where the grim discovery was made on Monday morning is accessible only by the canal towpath off Low Mill Lane, which serves a number of firms and industrial complexes.

The sex and identity of the body have not yet been made public by detectives from West Yorkshire’s Homicide and Major Enquiry team, who are heading the investigation.

But there is no link with missing Dewsbury man Daniel France, who vanished at the weekend.

Police have appealed for help in finding the 38-year-old, who disappeared on Saturday.

It is thought the body found by the canal may have been there for some considerable time.

The site was sealed for more most of Monday and yesterday by police.
