The man leading the inquiry, Detective Superintendent Mick Turner believes it shows how the victim would have looked.

He also now has new information that the victim had a deformity to his legs - probably from a childhood disease - and would have walked in an unusual way, possibly limping or leaning to one side.

The victim's skeleton was found partially submerged in water in a pond in a field off Back Lane, Charnock Richard by a woman out walking her dog around 6pm on Friday, July 26.

He had suffered head injuries that were probably the result of a deliberate assault. Experts from Glasgow University's Human Identification Unit prepared a computer image showing him to be more than likely of Asian origin.

Following detailed tests it was established that the victim was aged between 20 and 30 when he died. He was between 5ft 6ins and 5ft 8ins, slender. No exact cause of death has been established and police believe the body had been lying where it was found for up to 12 months.

Appeals for information have been made in Asian languages like Urdu, Hindi and Gujerati with posters being distributed among minority ethnic communities in Lancashire and surrounding police force areas.

The life-sized model has been created by Dr Caroline Wilkinson at Manchester University.

A major police investigation involving more than 30 officers was launched after a preliminary examination of the bones by a Home Office pathologist confirmed they were human.
