Detectives have seized suspected cannabis with an estimated street value of £1.7 million in Co Tyrone.
The haul was recovered following a search of a lorry in Cookstown on Sunday.
Detective Chief Inspector Gail McCormick said: “It has now been taken away for further forensic examination.
“A 41-year-old man has been arrested on suspicion of being concerned in the supply of controlled drugs and possession of class B drugs with intent to supply and he remains in custody at this time.
“As a result of this search a large quantity of suspected dangerous controlled drugs are now safely off our streets.
“Drugs have no place in our community, and I am making a direct appeal to anyone with information about the illicit supply, possession or misuse of drugs to contact police on the non-emergency number 101.”
