Hampshire Police forensic officers photograph the tent at the Holmsley campsite near Bransgore in the New Forest after the death of a young girl
Investigators are attempting to establish the exact circumstances surrounding the "tragic" death of a six-year-old girl who was found dead on a campsite on the first day of the Easter weekend.
It comes after two people detained on suspicion of murder following the incident at the Holmsley campsite in the New Forest, Hampshire, were released without charge.
The pair - a 30-year-old man and a 40-year-old woman, both from Gosport in Hampshire - were held by police after the youngster was discovered "fitting" during the early hours of Friday morning.
However, they were later discharged from custody following the results of a post-mortem examination which indicated there were no suspicious circumstances surrounding the death.
The young girl, who is expected to be named by police later on Saturday, was rushed to Southampton General Hospital after suffering a cardiac arrest at the holiday park and pronounced dead a short time later.
Teams of crime officers from Hampshire Police descended on the campsite and began to examine the family-sized tent the girl was staying in, but on Friday night the force revealed there was no foul play involved.
A Hampshire Police spokeswoman said: "The results of a post-mortem examination conducted at Southampton General Hospital have indicated that there are no suspicious circumstances."
Saying the two arrests were "necessary as a result of a report from experienced medical professionals", she added: "The girl's death is no longer being treated as suspicious but a tragic incident. An investigation into the cause of the girl's death is ongoing.
"As with all investigations into the death of a child we will now be working with partner agencies to support the family throughout the investigation process."
