Bomb disposal experts were called to a village after police found "suspicious items" during a search.
Cambridgeshire Police made the discovery at a property in Brick Lane, Mepal, near Ely, on Wednesday and some homes nearby were evacuated.
A spokesperson said a 100m (328ft) cordon was put in place around the property, while specialist explosive ordnance officers "disposed of the items safely".
A 30-year-old man was arrested on suspicion of stalking, criminal damage, threats to kill, possession of a firearm and possession of an explosive substance.

Police said the man remained in custody in Cambridge while investigations continued.
