Officers from the Paramilitary Crime Task Force investigating criminality linked to north Antrim UDA, assisted by officers from PSNI Tactical Support Group, carried out a proactive search at two addresses in the Ballymoney area on Tuesday.
A number of items have been seized which are subject to ongoing investigation.
Detective Inspector Brennan said: “Anyone with information about any criminality linked to paramilitaries should contact police on 101 or anonymously through the Crimestoppers charity on 0800 555 111, which gives people the power to speak up and stop crime.”
