A man was arrested last night for questioning about an stg£18 million drugs seizure in the North.
Two people have already been charged with possession of the cannabis haul, which weighed three-and-a-half tons and was found in a freight company warehouse at Newtownards, Co Down last week.
A Northern Ireland freight company boss and a lorry driver from Sunderland in the UK have already been charged with possessing the drugs with intent to supply.
The haul was discovered by police in a warehouse hidden in pallets of hollowed-out doors which had been transported from Madrid.
