The Organised Crime Branch arrested a 33-year-old man in the Waterside on Monday, September 7, following a house search.
The arrest is linked to the seizure of a haul of steroids worth over £30,000, which was intercepted in England, en route to an address in the city. A large quantity of suspected counterfeit DVDs and electronic equipment was also recovered.
The man was arrested on suspicion of attempted possession of class C controlled drugs, attempted possession of class C controlled drugs with intent to supply, conspiracy to supply class C controlled drugs, importation of class C drugs and copyright offences.
He is currently in custody assisting officers with their enquiries.
Detective Inspector Tom McClure said: “We are grateful to our colleagues in the National Crime Agency for their timely assistance in this intervention. The PSNI is committed to policing the threat posed by drugs in Northern Ireland and will continue to work with our colleagues in NCA and elsewhere in relation to detecting those involved in the illegal supply of drugs.”
