Last week, Portlaoise Athletic Club suffered the same fate.
A second sports organisation in the midlands has seen their facilities vandalised in the space of seven days.
The committee of St. Carthages AFC in Offaly say it'll cost around €3,500 to repair the damage done to their windows and dressing rooms.
It comes in the wake of a similar act of criminal damage at Portlaoise Athletic Club last week.
St. Carthages Assistant Manager Seamus Holleran says it's a huge setback:
In a post on Facebook the St. Carthages say actions like this are devastating to rural clubs.
They're going to run a last man standing competition in order to fundraise to repair the damage.

To say as a club we are upset and angry is an understatement. We got a message to say that some windows had been broken...
