The behaviour was reckless, caused great distress and could have resulted in serious injury.
On behalf of Falkirk Football Club and its supporters we have apologised to The New Saints and their supporters for the inevitable distress caused.
This type of occurrence is previously unknown at our stadium and will not be tolerated.
As such we are working the Police, our security partners, our supporters’ groups, and supporters’ groups of other clubs to identify and hold to account those who planned and perpetrated these events.
Anyone identified will be made known to police and will receive the most severe sanctions from the club.
If anyone has any information which could be useful, we encourage you to contact the club in confidence to help us with the investigations.
We wish to sincerely thank our stewards and Police Scotland for their selfless action to protect innocent parties and wish those hurt doing so a swift recovery.
Finally we wish to thank the vast majority of Falkirk supporters who attended the game on Saturday, once again in great numbers, for your fantastic backing and the positive atmosphere which you created."
