The 54-year-old man, a civilian member of police staff, was held on suspicion of misconduct in public office.
He was detained in Co Antrim on Tuesday by officers from the Serious Crime Branch and was taken to a police station in Belfast for questioning.
A police spokesman said he was released pending a report to the Public Prosecution Service on Tuesday evening.
Seven men including a 48-year-old police officer, a retired police officer and a 37-year-old member of police staff have previously been arrested as part of the same investigation.
The police officer and 37-year-old member of staff have been suspended and files on all seven suspects are being prepared for submission to the Public Prosecution Service.
A spokesperson for the PSNI said another man was interviewed last week as a result of the probe.
The statement continued: "Detectives are also preparing a file on a 49-year-old man following inquiries into bribery and misconduct in public office which were initiated by this investigation.
"He voluntarily attended a police station in Belfast last week for interview."
