Keith McGrellis said: “This was a totally despicable attack. Northern Ireland is transforming and we will not let anyone prevent progress. People want peace and want to be able to get on with their lives without being subjected to incidents of this nature.
“It is deeply distressing that this attack happened when a couple and two children were in the house. Thankfully no-one was injured but this must have been an extremely frightening experience for them. Anyone with information on this attack should contact police immediately.”
