Cannabis plants with a street value of £450,000 have been seized in Co Antrim.
They were discovered when officers from the PSNI's organised crime branch swooped on a property in the Old Portglenone Road area of Ahoghill.
Chief Inspector John Magill said the haul had dealt a massive blow to drug dealers.
"It is a significant find and one that puts the criminals and organised crime gangs on the back foot," he said.
"Police are committed to working with communities to reduce the threat posed by drugs and make Northern Ireland a safer place for everyone."
No arrests were made during Monday's raid but police said investigations were continuing.
