A three-year-old boy found "unresponsive" in a swimming pool last night has died, police said.
The child was reported as missing to Wiltshire Police at 7pm yesterday but was discovered in a nearby pool 20 minutes later.
He received emergency treatment at the scene, in Upavon, but remained unresponsive and was airlifted to Southampton General Hospital.
A spokeswoman for Wiltshire Police said the boy had "tragically passed away in the early hours of this morning".
"Formal identification is yet to take place," the force spokeswoman said.
"Wiltshire Police will now work with Hampshire Constabulary and partner agencies to prepare a report for the coroner's office."
