Shocked St Albans residents called police at around midday today after they found an artillery shell on a grass verge in Thirlmere Drive.
Herts police officers attended and a cordon was put in place while the Explosive Ordnance Disposal assessed the item and then removed it.
The cordon was lifted at around 1.45pm.
Further enquiries established that the item had belonged to a collector and was thrown into a skip during a clear out several days ago.
Someone else had taken it out, while looking for anything of interest inside the skip, and then left it on the ground.
