A worker is in a critical condition after being pulled from a lake on the Queen's Sandringham estate.
Reports suggest that an estate worker, believed to be in his 30s, was operating a ride-on lawn mower when he fell into the lower lake yesterday.
Emergency services were called to the Norfolk retreat at around 1.30pm.
A spokesman for Norfolk Police said: "The man was retrieved from the water and was taken to Addenbrooke's Hospital by air ambulance for treatment. He is currently described as being in a critical condition."
