The discovery of a burnt out car in Thetford sparked a hunt for suspects from the police helicopter and dog units.

The car, believed to be an Audi A4, was found in the middle of Barnham Cross Common at around 11.40pm last night.

Fire crews attended the scene and extinguished the fire with hand appliances.

Police also attended, and searched the area for suspects with the assistance of the police helicopter and dog units.

No one was arrested, but a police spokesman said the incident was being treated as a suspected arson.

The common lies next to the Barnham Cross Common Estate, which saw a spate of arson incidents in August.

Anyone with information is being urged to call police on 101, citing CAD number 608.
