Dozens of emergency services personnel from across the county have been involved in a major search operation tonight.
It follows more than one report to 999 claiming they witnessed a parachutist coming down on a pylon close to Sutton Benger, near Chippenham, at around 7pm.
Both the police helicopter and Wiltshire Air Ambulance were sent to the scene, but despite a coordinated search of pylons and fields between Swindon and Chippenham, no casualty was found.
The last location checked was a field in Kington St Michael, where fire crews from Swindon (x2), Chippenham (x2), Trowbridge (x2) were all in attendance lining a country road near the M4 underpass.
Emergency services were stood down at around 8.15pm following the hour-long search.
Wiltshire Police is asking anyone with information to contact them immediately by calling 101 and quoting log 284 of today.
