There's growing concern for the welfare of a 15-year-old boy who's been missing for 11 days, and who was last seen in Sussex.
Arthur Greenslade is from Aylesbury in Buckinghamshire, but his last known sighting was in Brighton a week last Sunday, April the 18th.
Police describe Arthur as being 5'6" tall, of slim build, and with brown hair.
It's thought he could either be in or near Brighton, but he also has links to London.
