The man, who has not been named for fear of affecting his career, and was off duty at the time, claimed the beings were inspecting a new crop circle in the middle of a field.
According to a video released about the sighting, the officer saw distant activity and got a strange feeling before stopping his car to investigate.
The video claims as he approached the three "men", he could see they were all taller than six feet, with long blond hair, but then heard “the sound of static electricity” before the trio ran away ”faster than any man he had ever seen”.
The officer described the events which allegedly happened on July 6, 2009, as almost "unreal".
He said he drove straight back to Marlborough in Wiltshire, and later contacted paranormal experts.
