Three men were being questioned by police today after the seizure of a large quantity of amphetamines in Antrim.
The drugs had a street value of around £180,000, said the PSNI.
The men, two aged 27 and one aged 25, were detained in the town last night after the stop and search of a vehicle.
Meanwhile, a 31-year-old man has been charged with possession of a Class B drug with intent to supply and cultivating cannabis.
The charges follow the discovery of a large number of cannabis plants growing at a house in the Lurgan area of Co Armagh yesterday. The man is due in court at Craigavon on June 11.
