It doesn't matter whether it was the right person or not. Having a high-viz jacket or a little card strapped to your arm does give you carte-blanche to go around assaulting members of the public that you happen to take a dislike to.
Granted, we don't have all the evidence but thus far, there is nothing in that video to suggest that the steward (who is acting as a representative of WWRLFC), is acting in a way that was necessary to defend himself from harm.
A simple "we are aware of reports of an incident and assiting the police with their enquiries" would suffice from the club.
