A march aimed at highlighting the disappearance of Mary Boyle in Donegal over 30 years ago will take place in Ballyshannon today.

The six-year-old girl disappeared in Cashelard near Ballyshannon in 1977.

Mary vanished while playing outside her grandparents' home.

Earlier this week gardaí confirmed that a second review of the case into her disappearance is being carried out by the Serious Crime Review Team.

The march will get underway in the town at 2.00pm, before walking to the local garda station.

Local resident Naomi Brady is organising the event.
