A man has died after being found unconscious in a pond in Wattisham.
The man, in his fifties, was discovered at a property on Clay Hill Lane just before 6pm yesterday evening.
It is believed he was a builder undertaking work at the property.
East of England Ambulance Service rushed to the scene deploying three vehicles and volunteer Dr Andy Mason from the Suffolk Accident Rescue Service (SARS).
A spokesman from the East of England Ambulance service said on arrival at the scene crews fought to revive the man.
He said: “We were called at 5.59 and sent two community first responders, an ambulance, a rapid response vehicle, a duty manager and a SARS doctor at the scene.
“Crews did their best to try and revive the man.
“They were there within two minutes with a defibrillator to carry out life saving treatment including CPR.”
The man, in a critical condition, was flown to Ipswich Hospital by an RAF Sea King helicopter from nearby Wattisham Airfield.
The SARS doctor and East of England Ambulance Service paramedic accompanied him to hospital in the aircraft.
A Suffolk Accident Rescue Service spokesman said: “Despite everyone’s best efforts the man died in hospital overnight.
“Out thoughts are with his family and friends at this difficult time.”
