Police are asking for help to trace a teenager who has gone missing from Stevenage.

Benedict Blackwood, 17, was last seen at his home in Stevenage at 4pm last Wednesday, February 22.

It is believed he may have travelled to Kent, but has links in both Stevenage and North Herts.

Benedict, who also uses the names Ben or Benny Williams, is described as black, around 5ft 8in tall and of slim build with short, black hair.

He was last seen wearing a navy coat, a black tracksuit and black Nike Air Max trainers. He was carrying a black Nike bag with white writing on it.

Officers are growing increasingly concerned for his welfare.

Anyone who has seen him or who knows where he is should call Herts police on 101.
