Bomb disposal teams and police cordoned off an area in Luton today (Friday 13) after what is thought to have been a cannonball was found on a building site.
Hitchin Road was closed between Stopsley Way and Stockingstone Road.
Police were called at around 10.30am after someone reported seeing something suspicious on a nearby construction site.
Bedfordshire police say the explosive ordnance disposal team were called as a precaution. The roads have since reopened.
