David Ford MLA said: “The local community will be horrified at news of this attack.
“Those involved in this attack have an agenda of fear and we need people with information to come forward and help police catch these evil elements.
“My thoughts are with those who were in the house at the time of this attack as they try to get over this ordeal.”
