Part of the beach between Walcott and Happisburgh in North Norfolk was closed after a fossil hunter came across what appeared to be an unexploded shell washed up on the beach. The man alerted the Coastguard and they marked the location of the device, which was situated on the high tide line.
An Explosive Ordnance Disposal (EOD) team was called in from Colchester. They assessed the shell as being safe to move and took it away for disposal.
Coastal erosion along this stretch of Norfolk, in addition to North Sea storms, regularly results in Unexploded Ordnance (UXO) being exposed or washed up on beaches.
