Keith McGrellis said: “I am appalled at this trouble. People want to live free from incidents of this nature and those who carry out acts like this must not be allowed to cause instability in our society.
“Northern Ireland is moving forward to a more peaceful and shared future and the progress made in recent years must not be hampered by the actions of a few individuals.
“I appeal to anyone with information on this incident to contact police immediately because those involved in such activities must be brought to justice.”
