Agree with this Andy. If he's sworn at the lad then he should know better, regardless of provocation, and should be reprimanded/fined by OAFC and told to make a formally apology to the lad and to SUFC.
If it transpires that he has used racially abusive terms then he deserved the book thrown at him.
However, if it transpires that the allegations are false and fabricated by a group of SUFC supporters, I'd expect the police to pursue and charge those fans with wasting police time and/or attempting to pervert the course of justice.
