A man has died in a helicopter crash in Cambridgeshire.
East of England Ambulance Service crews were called at 11.30am to reports that an aircraft carrying one person had landed in a field off Lancaster Road in Witchford.
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.
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."
At the crash site, Chief Inspector Dave Sargent, from Cambridgeshire Police, said recovery of the helicopter would begin tomorrow and that the Air Accident Investigation Unit would begin a probe into the cause of the incident.
Police said later a cordon would remain in place overnight, adding that the helicopter was not expected to be moved before tomorrow at the earliest.
