The dig to recover a Spitfire from marshland in Holme has been suspended after skeletal remains were found.
Archeologists have been working at the crash site of the plane at Holme Lode Farm since Monday. The fighter crashed 75 years ago.
Pilot officer Harold Edwin Penketh died in the crash, which happened on November 22 1940, and his body was recovered and buried in Brighton.
It is believed the bone discovered belonged to the pilot.
Today a spokesman from Oxford Archeology East, who are carrying out the dig, said: “Oxford Archaeology East has suspended the fen Spitfire dig because we suspect we have found human skeletal remains, and we have contacted the Coroner and we will follow their instruction.”
A spokesman for Cambridgeshire police said they had been called to the scene.
The case has been passed to the Huntingdonshire coroner.
