A man and woman in their 30s have been arrested after a suspected cocaine factory was shut down, police said.
Drugs with an estimated street value of £600,000 were seized along with £300,000 cash and three Mercedes cars during the overnight police operation.
Superintendent Stephen Reid said the raid had been intelligence led.
He said: “This is a very substantial haul in which three luxury cars were seized on the suspicion that they were purchased with the proceeds of crime.
“This is a prime example of PSNI officers keeping people safe.”
An imitation firearm, 30 mobile phones, amphetamines, drugs paraphernalia including a suspected cocaine press and steroids were also removed when officers swooped on properties in the Ballyhenry and Dalewood areas of Newtownabbey, Co Antrim.
The 33-year-old man was arrested on suspicion of six offences including possession of class A drugs with intent to supply.
The 31-year-old woman is being questioned about nine alleged offences including conspiracy to supply class A and B drugs and possessing criminal property.
The PSNI said both suspects were assisting police with their inquiries.
