AN ARDROSSAN teenager has been given unpaid work after he admitted a breach of the peace earlier this year.  Daniel Thomas Docherty, 19, of McDowall Avenue, admitted behaving in a threatening or abusive manner, by shouting, swearing and committing a breach of the peace.  Docherty was sentenced to 90 hours of work to be completed in a period of three months at Kilmarnock Sheriff Court last week.
