When he was found, he was wearing a pair of well-used Caterpillar boots; a studded leather belt; a tweed-like Jasper Conran coat worn under a dark blue body warmer; a thick-knit jumper with a zipped collar; a blue and red-checked shirt; and dark blue jeans.

Found in a pocket were a pair of metal-rimmed glasses in a hard, blue case from Boots.

It is believed he had been in the water for some time.

Detective Sergeant Chris Percival, who is leading the search, said: “Usually in such tragic cases, we can quickly identify the person and inform their next of kin, so it is unfortunate that with this man we have so little to go on.

“It is most likely this man is from Worcestershire or Warwickshire, so I would like to appeal to anyone who thinks they recognise the description and the clothes he was wearing to contact West Mercia Police straight away.”

DS Percival can be contacted at Worcester CID on the non-emergency police number 101 or information can be passed anonymously through Crimestoppers on 0800 555 111 or www.crimestoppers-uk.org. Please quote the reference number 151s for 19th February.
