A 21-YEAR-OLD woman found dead at a campsite has been named.

The body of Sarah Clayton, from Yapton, near Arundel, was discovered in a tent at the Buckle Holiday Park in Marine Parade, Seaford, on Sunday.

A 28-year-old man known to her was later arrested on suspicion of murder, and remains in police custody.

Officers are not looking for anyone else in connection with Ms Clayton's death.

A 50th birthday party took place at the site over the weekend, and the force is looking to speak to people who were there.

A Home Office pathologist was carrying out a post-mortem this afternoon to establish the cause of death.

Police were called shortly after 7am, and the man was arrested at about the same time.

According to her Facebook profile, Ms Clayton had got engaged to boyfriend Chris Cole on April 23.

Friend Molly Feegrade wrote on Facebook today: "Woken up to some shocking news... rest in peace Sarah Clayton far too young to go.

"Thoughts are with your family."

Detective Chief Inspector Emma Heater, of the Sussex and Surrey Major Crime Team, who is leading the investigation, said: "Although we're not looking for anyone else in connection with Sarah's death we are still seeking witnesses or anyone with information that may assist us.

"In particular we'd like to talk to dog walkers or other pedestrians who used a footpath through the site during the early hours of Sunday, and people who were there to attend a 50th birthday party over the weekend.

"They may have seen or heard something unusual or suspicious that we need to know about."

Anyone with information about Ms Clayton's death should call Sussex Police on 101 quoting Operation Cobblestone.
