I had a chat to my flatty about it, also known as "the_narc", he is a general duties cop like the one you would be trying to convince to do something about it. Whilst it is possible that the police could do something, he thinks it would be a very bored and keen copper who would touch this. 99.999% will brush it off as a civil matter.
Better get a Lawyer....
The problem being whist he has kept the trophy too long, the club did give it to him willingly in the first place.
he can always state the old Australian Armed Forces addage..
"Did I sign for it ??"
unfortunate but true.
has he still got the trophy himself ??
maybe we should divert the supercruise! and pay a visit.
