The black "dare2be" jacket and bracelets - one of which is thought to be a 'Kara' worn by Sikhs - were worn by the man before he died, along with a navy blue George at Asda T-shirt and dark-coloured tracksuit bottoms.
The man lay undiscovered for at least three years until a road worker madet he grim discovery at the side of the eastbound entry sliproad of junction four of the M54, near Telford in Shropshire.

Det Ch Insp Neil Jamieson, who is leading the investigation, said the cause of death was still unknown.
We are keeping an open mind as to how the man came to be in such a location and how he died; however, I cannot rule out that he may have been subjected to a crime, and that is something the public can help me with.
