Three men aged 31 and 42 have been arrested by police on suspicion of a range of drugs offences after police stopped a car in the Castlewellan area on.
Police uncovered a quantity of suspected heroin and suspected diazepam tablets.
A follow up search at a nearby address revealed further quantities of what is believed to be heroin and prescription medication.
A 60-year old man at the address was subsequently arrested at that location on suspicion of drugs offences.
All three remain in custody this morning.
