A 28-year-old man has been arrested on suspicion of murder after a 21-year-old woman was found dead inside a tent at a campsite.
Police were called to the caravan and camping site at Marine Parade, Seaford, West Sussex, at 7am on Sunday where the woman was discovered.
A spokesman for Sussex Police said: "A 28-year-old man from Littlehampton has been arrested on suspicion of murder.
"No-one else is currently being sought in connection with the death."
Detective Inspector Andy Eggleton said: "We would like to speak to anyone who used a footpath giving access to the campsite between midnight and 6.30am on Sunday and who may have seen or heard anything suspicious.
"We are also aware of a 50th birthday party having taken place at the campsite this weekend and again would ask anyone who attended to come forward please."
