Given Ethel's answer, I guess you might have a case for slander (I believe it's libel if it's written, slander if it's spoken) if anyone he told was to assault you or damage your property because of what he said, as well as your having a case against those people directly.
It will all come out court, and he'll most likely find out then who grassed him up, but if he causes you any distress over the matter, either before, during or after his 'trial', then you should report him immediately.
