A 43-year-old man was arrested by police investigating the drug related death of a woman three years ago.
The woman, in her 30s, died in John Street Court in Newtownards in 2017.
PSNI Inspector Jonathan Francey said: "The male was detained in the Lyndhurst Crescent area of Belfast yesterday on suspicion of drug supply offences in connection with the death.
"A follow-up search at a house in Meadow Close uncovered a large quantity of class A, B and C drugs including suspected diazepam and Xanax, along with a significant amount of counterfeit goods.
"The male was additionally arrested on suspicion of further drugs offences as well as theft, fraud and counterfeiting offences.”
The man has been released on bail pending further enquiries.
