Two people have been arrested following the death of a six-year-old girl who was taken to hospital from a campsite early today, police said.
Paramedics were called to the Holmsley campsite, in Bransgore, in Hampshire, just after midnight.
A spokesman for South Central Ambulance Service said the girl was "fitting and not breathing".
He went on: "A double-manned ambulance was sent with an emergency care practitioner.
"The child went into cardiac arrest and adrenalin was administered."
She was taken to Southampton General Hospital where she was later pronounced dead.
Speaking at the scene, Sergeant Heather McNicol, from Hampshire Police, said: "Overnight we were called to Holmsley campsite after the death of a six-year-old girl.
"Police are treating the death as possibly suspicious because of the age of the little girl.
"Two people have been arrested."
A fellow camper told the Southampton Echo they had no idea about the girl's death, saying: “Blimey, you come away on holiday for Easter and then something like this happens.”
