Detectives investigating the death of a man in Dudley believe he may have been a lorry driver, whose load had been stolen the previous day.
An inquiry was launched after the body of the man was found by a passing member of the public on Vale Road, Darby End, near to the canal bridge at 6.50am on Monday.
Police believe the 57-year-old was a lorry driver from Poland who had been travelling through the Black Country with a load of televisions in his wagon.
The lorry has subsequently been recovered from a trading estate in West Bromwich. The trailer had been emptied of its load.
DCI Steve Bimson from West Midlands CID said: "We don’t yet know the exact events leading up to this man’s death, or what the circumstances are in which he died.
"Tests have proved inconclusive in determining a cause of death and so we have to keep an open mind at this stage.
"The lorry in which we believe he was travelling was found dumped on Vectra Industrial Estate in Hill Top, West Bromwich, at around 10am on Monday. Some time before that his load was taken.
"We believe that unknown persons have robbed the vehicle in another location and then driven the lorry to this trading estate, where it was dumped.
"It’s not clear how the deceased man ended up in Dudley, however we know that the lorry travelled through Oldbury over the weekend, and we appeal for any witnesses who saw the wagon on Saturday or Sunday to come forward and pass on the information."
The load of televisions stolen from the vehicle are described as LG LCD flatscreen TVs, sized 47in. Some were in 3D format.
DCI Bimson added: "We want to know what has happened to these TVs. They may well be being offered for sale somewhere, and we urge anyone who is offered such items to get in touch."
Police have not revealed the dead man's identity as not all relatives have been informed of his death.
