In south Belfast, the PSNI confiscated suspected Class B drugs with a street value of up to £90,000.
The seizure was made on Sunday by detectives from PSNI Organised Crime in Belfast, in collaboration with partners from the Organised Crime Task Force.
A 53-year-old man was arrested after a house in the city’s south was searched as part of the investigation. Police are interrogating him.
Detective Inspector Kelly, from the Organised Crime Unit, said: “We remain fully committed to tackling the scourge of drugs in our communities and we will continue to proactively investigate and carry out searches linked to the drugs trade.
“The very simple reality is that the sale, supply and consumption of these drugs is doing nothing but ruining lives and lining the pockets of organised criminals.”
He added: “We are determined to disrupt their activity and anyone involved in the drugs trade. Anyone tempted to become involved in illegal drugs should be under no illusion; we will seek to identify them, arrest them and place them before the courts.
“I again repeat our appeal to anyone who can help us identify suspects or provide any information about suspected drug dealing in their area to call the non-emergency number 101.
