A group of residents in Buxton, near Norwich, returned to their homes last night following the safe removal of a suspicious device from outside a local residence. Police were called to Coltishall Road shortly after 11am yesterday morning to reports of a device found outside a property.
A 100 metre cordon was put in place and an evacuation of six properties took place to ensure the public's safety. Initial examination indicated the object was safe to remove and it has subsequently been transferred to a forensic laboratory for further examination.
The cordon was lifted at around 8.30pm last night. Police continue to investigate the circumstances surrounding the incident, which is believed to be targeted at an individual.
