An AK-47 and an Uzi machine gun were among weapons found by police searching a cottage in Suffolk, it has emerged.
Police said 50 officers had been involved in investigating the “significant” find in Potash Lane, Wyverstone, since 27 March.
A search of the area will continue for at least a week. Wyverstone Parish Council chairman James Arnold has been charged with firearms offences.
Mr Arnold, 49, of Potash Lane, is due at Ipswich Crown Court on 1 May.
He is accused of being in possession of a self-loading rifle gun, a bolt-action shotgun, a Uzi machine gun and an AK-47 assault rifle.
Police said they were initially called to the house over an allegation of assault, and then carried out a search warrant.
