Detectives have said the arrest of a 24-year-old woman is 'significant' as part of an international investigation into the supply of 'skunk' cannabis.
The suspect was arrested in the Birmingham area yesterday and has been brought to Northern Ireland for questioning following a series of searches in England.
The officer leading the investigation, Detective Inspector Andy Dunlop, said: “I believe this is a significant arrest and this investigation is making substantial progress. To date, we have arrested 13 people, eight of whom have been charged.
"We have seized more than £2 million worth of cannabis in Northern Ireland in recent months and seized large amounts of cash.
“We are maintaining close contact with our colleagues in the Italian Carabiniere, as arrests and seizures have been made in Italy. We are also working closely with the National Crime Agency as well as a number of other law enforcement agencies in the UK and Ireland.
“Our objective is to ensure we identify and apprehend as many of those allegedly involved in this criminality and bring them before the courts, as well as seize drugs and as many criminal assets as possible. Our inquiries will continue for some time and there will be further arrests.”
The woman will be questioned at a police station in Belfast.
To date 13 people have been arrested, eight of whom have been charged while more than £2million worth of cannabis has been seized in Northern Ireland.
Two have been released pending report to PPS, two released pending further police enquiries and one remains in custody.
