A 64-year-old man has been arrested in connection with the disappearance of Mary Boyle, a six-year-old girl who went missing in 1977.


Mary’s body was never found, and it remains the oldest missing person’s case in the country.


Mary went missing on a family visit to her grandparents in Donegal. The case has been reviewed several times, most recently being reopened in 2011.


The arrest comes after new information was discovered by the Review Team, which is based in the Northern Region.


The man is being held for questioning in Mullingar Station. He has been arrested under the Criminal Justice Act 1984, meaning he can be held for up to 24 hours.


A Family Liaison Officer is keeping Mary’s mother Ann Boyle up to date with developments in the case.


Assistant Commissioner Northern Region Kieran Kenny appealed for more information relating to the little girls abduction.


“We are appealing for anyone with any information on the circumstances around Mary’s disappearance to contact us,” he stated.


“Even something that people may have thought was insignificant at the time could help us advance the continuing investigation.”


Anyone with information is asked to contact the Incident Room at Ballyshannon Garda Station at 071 9858530 or the Garda Confidential Line 1800 666 111.
