A mystery man is in a critical condition in hospital after a collision with a car on a main Stevenage road.

The pedestrian who has yet to be identified was involved in a collision with a dark blue Lexus IS250 saloon travelling south on Grace Way shortly before 10pm last night (Tuesday).

He was taken to Lister Hospital by paramedics before being transferred to Addenbrooke’s Hospital in Cambridge where he remains in a critical condition.

Police are appealing for help to identify the man and for witnesses to the incident to come forward.

Pc Bob Hauxwell, from the Bedfordshire and Hertfordshire Roads Policing Unit said: “Despite extensive enquiries we have yet to identify the victim of this collision, who remains in a critical condition. Someone somewhere will be missing this man.

“Perhaps you have a son, brother, partner or housemate who has not come home, or a colleague who has not turned up for work? If you recognise this information I would urge anyone who may recognise his description or the description of his clothing to get in touch with us immediately.”

The man is described as white, in his early to mid 30s and approximately 5 ft 10 ins tall with proportional build. He has blue-green eyes and brown hair which is short but not cropped, and a couple of day’s stubble growth.

He has an appendix scar. He was not wearing any jewellery and the only possessions found on him were two unmarked keys.

At the time of the collision he was wearing a dark grey leather jacket with a grey fur-lined collar, a black long-sleeved top, described as thicker than a t-shirt, but thinner than a sweater, a red t-shirt with blue piping round the collar and another red t-shirt under that with an image of a footballer kicking a ball and the words ‘English footballers score more’.

He was also wearing dark blue trousers, dark coloured lace-up work type shoes and black socks.

If you think you know this man call the non-emergency number 101 or Crimestoppers on 0800 555 111.

A 38-year-old Stevenage man was arrested on suspicion of dangerous driving. He has been bailed until March 24.
