A prison officer is due in court today charged with attempting to smuggle drugs into Maghaberry Prison.
The 23-year-old man has been charged with a total of 16 offences including conspiracy to supply class A, B and C drugs, possessing class A, B and C drugs with intent to supply and misconduct in public office.
He is expected to appear at Lisburn Magistrates Court today.
The charges follow an investigation by PSNI Criminal Investigation Branch into the trafficking of prohibited items into Maghaberry Prison.
On Saturday, a 55-year-old woman arrested as part of the same investigation was released on bail pending further enquiries.
A 26-year-old woman who had also been arrested was released earlier on bail pending further enquiries.
They were detained on Friday after searches of properties in Lisburn and Dungannon.
A quantity of drugs and associated paraphernalia was also recovered during the operation.
Detective Chief Inspector Brian Foster, from the PSNI's Criminal Investigation Branch, said at the time: "During the searches in HMP Maghaberry and in the Lisburn and Dungannon areas today, detectives seized a quantity of suspected Class A and Class B controlled drugs and drugs paraphernalia."
Head of the Northern Ireland Prison Service, Ronnie Armour, said: "Removing dangerous drugs from Maghaberry will help to keep staff and prisoners safe. I would commend everyone involved in this operation."
