Relatives of a missing 15-year-old have urged him to contact them or his parents to let them know he is safe.
Police believe Jerome Thomas, who was last seen walking from his home in Gwbert, near Cardigan, Wales, on Monday, could be headed for Crawley.
The teenager's grandparents and an uncle, aunt and two cousins live in the Tollgate Hill area of the town.
His uncle, Jude Singleton, said: "If he has made his way down here, hopefully he would get in touch with somebody down here, at least to let us know he is safe and well.
"We are all worried. He has never done this before. He has been a very good lad - there is no reason why he should do this."
Police are also checking whether the 15-year-old has gone to south London, where he has more cousins.
His parents believe Jerome has fled home because of exam pressure in the run-up to sitting his GCSEs.
