Some of their facilities are now unusable.
Players and members of a midlands sports club club have been left "disheartened" following extensive damage to their club house.
The toilets at Ballymore GAA's facility have been rendered unusable following the incident, and the wall is covered in cracks and dents.
They are currently also unable to host club championship games.
The club's chairperson, Ciaran McCormack is appealing for anyone who might have information to contact Gardaí:
In a statement to Midlands 103, Gardaí say they are "investigating an incident of criminal damage at a sports ground in Westmeath which is believed to have occurred over the weekend.
Damage was caused to the wall of a building on the grounds.
Investigations are ongoing."
