Around £900,000 worth of drugs has been seized in a vehicle on the A1.
The seizure was made during the course of a cross-border operation into organised crime at Loughbrickland on Wednesday.
Various agencies were involved, with ANPR Interceptor Team officers supporting local PSNI officers, Tactical Support Group and Organised Crime Unit.
A PSNI spokesperson said: “Police were also joined by our Agency partners from Her Majesty’s Revenue and Customs (HMRC) and Driver and Vehicle Standards Agency (DVSA).
“During this operation which took place on the A1 dual carriageway one driver was arrested after a search of a vehicle revealed a large amount of cannabis with an estimated street value of around £900,000.
“The driver remains in custody assisting police with their enquiries.”
The seizure has been welcomed by DUP Upper Bann MLA Carla Lockhart.
She said: “I would commend the PSNI for this significant and sophisticated operation. Taking £900k of drugs off the streets is very welcome and no doubt will save lives. Drugs ruin lives and communities and there is no place for them in our society.
“I would encourage the public to continue to play their part in identifying drug dealers and reporting them to the Police. It is only with community involvement that operations like this can take place.
“I trust that those involved in this illegal activity will face the full force of the law. These individuals often play on the most vulnerable in our society.
“I would urge anyone who has any information to contact the PSNI on 101 or anonymously through Crimestoppers.”
