The body of a man has been found at Chasewater reservoir in Staffordshire.
Police were called to the park at around 6pm last night (Sunday) following reports two people had got into difficulty while in the water.
A young girl made it safely out of the water, but tragically a 21-year-old man died.
All three emergency services attended the scene, which also included three ambulances, two paramedic officers, the Hazardous Area Response Team and the Midlands Air Ambulances from Cosford and Staffordshire, both with doctors on board.
A West Midlands Ambulance Service spokesman said: “A number of boats and members of the public assisted in the search. Firefighters and members of the Hazardous Area Response Team were committed to the water.
“When the 21-year-old man was recovered, ambulance staff tried everything possible, but sadly it was not possible to save him and he was confirmed dead at the scene.
“Thankfully a young girl made it out of the water safely and was unhurt.”
The identities of the people involved are known to officers and their next of kin are being informed. They will be offered support by specially trained officers.
The Coroner will be informed of the incident.
Officers continue to investigate the circumstances around what happened and are appealing for anyone with information to call Staffordshire police on 101 quoting incident 654 of 30 June.
