|Sinn Fein representatives have condemned the attack on Tar Abhaile|
Repairing the damage at the Tar Abhaile office could be substantial, costing hundreds, if not thousands, of pounds, as the glass windows need to be replaced.
The incident in West End Park was condemned by Sinn Fein representatives, Sean McMonagle who works with Tar Abhaile, and The Moor district Councillor Colly Kelly.
Sean McMonagle described the vandals as "idiots, criminals and hoods" and questioned whether the attack may have been deliberately timed following Thursday's election.
