A man in his seventies has been arrested in connection with the 1984 murder of Kilkenny woman Marie Tierney.

The 34-year-old was reported missing on October 22 1984 having left her home at Clinstown, Jenkinstown, Co Kilkenny, at about 10.30pm the previous night in the family car.
The car was located at Newpark on October 22.
