A 54-year-old police staff member arrested in connection with a probe into vehicle contracts has been released pending a report to the Public Prosecution Service.
The PSNI announced both the arrest and his release on Tuesday.
The 54-year-old suspect was detained in Co Antrim on suspicion of misconduct in public office.
A number of arrests have been made as part of the inquiry and the chief constable of West Yorkshire Police was recently suspended pending an investigation by his former force in Northern Ireland.
Earlier on Tuesday a police spokesman said: “Detectives from serious crime branch investigating the awarding of a number of PSNI vehicle contracts have arrested a 54-year-old member of police staff in Co Antrim.
“He has been arrested on suspicion of misconduct in public office and has been taken to a police station in Belfast for questioning.”
The individual is a civilian employee, rather than a police officer.
He is the eighth individual to have been arrested as part of the ongoing probe into the vehicle contracts in Northern Ireland.
