POLICE have issued fresh pictures of a 14-year-old boy who has been missing for 15 days.

Officers at Avon and Somerset Police, who have taken on the case, say they are "increasingly worried" about the welfare of teenager Nasim.

They believe the youngster could be in Somerset, where he has links, "or anywhere in the country".

People are being urged to call 999 if they see him.

Nasim, who is from Preston, in Lancashire, say he was last seen at around 2.40pm on Tuesday, May 3, in Ashton-on-Ribble.

He is described as being 5ft 9ins to 6ft, with an Afro hairstyle, and he was last seen wearing a black Nike tracksuit, a beige t-shirt with a tiger print on the front, grey Nike Air 90s trainers, a grey North Face beanie hat and he had a white JD Sports string bag too.

DI Toby Hyder said: “We’re growing increasingly concerned for Nasim’s welfare.

“Although he has strong links to Somerset, he could still be in the general area where he went missing from, or anywhere else in the country.

"He’s just 14 years old, so please keep a look out for him and call us immediately if you see him.”

Call 999 if you see Nasim and give the call handler the reference number 5222111109.

If you have any other information which would help locate him, call 101 and give the same reference.
