A man has died after the helicopter he was flying in crashed into a field.
East of England Ambulance Service crews were called at 11.27am to reports that an aircraft carrying one person had landed in the field off Lancaster Road, Ely, Cambridgeshire.
A spokeswoman said: "Our hazardous area response team attended the incident as well as the air ambulance but the man, whose age is not known, was sadly declared deceased on scene.
"Our thoughts are with his family."
A spokesman for Cambridgeshire Police said emergency services were called to Witchford near Ely by a member of the public just before 11.30am.
He added: "A cordon has been set up around the crash site but no roads have been closed."
The field is behind a business park.
A witness told BBC Radio Cambridgeshire that they heard a bang and saw a black helicopter crash to the ground and land upside down.
The helicopter, thought to be a Robinson R22 two seater, is believed to have been flying from Manston Airport in Kent to Fenland Airfield near Spalding.
