In 1886 prolonged riots broke out in Belfast, of which you can read more about here.
A report was published outlining the injuries received by RIC officers and members of the military during the riots.  In this report is a Constable Patrick Buggy who was injured on 31 July 1886. The “nature and circumstance of injury” are given as “several blows of stones on body.” Under the question “how long unable to return to duty?” the answer of “not rendered non-effective” is given.
