I agree however you might find that they know of him already.

I do know of a young bloke fitting this description around the Honor Oak Road area who sometimes upsets people around here. He has what you might call special educational needs. However I appreciate that there might be others fitting that description.

You are being very positive but its not unknown for things like this person does to get out of hand and for someone to get really hurt so I wouldn't think twice about notifying the cops.
