Emergency services, including Norfolk Fire and Rescue Service, were called after a metal object was discovered while tree works were being carried out at the location not far from Norwich Road.

The Lidl supermarket on Norwich Road was closed and members of the public were asked to leave their cars in the car park until the situation was cleared. 

Officers put a 100m cordon in place for public safety and Explosive Ordnance Disposal attended the scene.

Around 30 households were advised to evacuate near to the scene and could attend Watton Sports Centre in Dereham Road, where a member of Breckland Council was on hand to help.

Late on Friday night people were allowed back to their homes and the cordon was lifted and roads reopened.
