The PSNI has appealed for the public to remain vigilant after a number of incidents in the North Down area over recent days.
North Down and Ards District Commander Johnston McDowell said police are currently investigating a linked series of incidents, including criminal damage and arson with intent to endanger life.
He says the incidents are linked to an "ongoing feud between two rival drug gangs operating under the banner of the Ulster Defence Association in the North Down and Ards areas".
