Detectives have seized Class B drugs worth approximately £1m in Antrim.
The seizure was made on Wednesday, following the arrest of a 38-year-old man in relation to the possession and supply of controlled drugs.
The suspect remains in police custody.
PSNI Detective Inspector Pete Mullan said: “Detectives will continue to protect communities from the harm of illegal drugs.
“This is one of the largest seizures of class B drugs in recent times.
“Not only have we stopped these drugs being sold on our streets, we have stopped the profits from lining the pockets of organised criminals.”
