A four-year-old boy has died after an "incident" at a holiday park swimming pool in Cumbria on Monday, police said.
Police are investigating the incident which took place at 4.40pm on Monday at a swimming pool in Old Park Wood Caravan Park, Grange-over-Sands.
The boy was taken to Furness General Hospital and was later transferred to Alder Hey Hospital in a critical condition but later died.
It is understood the boy was staying with his family at a lodge on the site, described on its website as "a luxury, private holiday park" set within the grounds of the Holker Estate.
An indoor heated swimming pool is available to guests at Old Park Wood.
In a statement, the force said: "Police can confirm that the four-year-old boy involved in this incident has sadly died.
"Detectives are continuing to investigate the incident but the death is not being treated as suspicious.
"Our thoughts are with the family at this difficult time."
A park spokesman said: "Our thoughts are with the boy and his family at this time."
