A couple and their 15-year-old daughter have escaped injury after a shotgun was fired through the living room window of their Lisburn home in the early hours.
The shooting happened in the Hillhall Park area just after midnight on Tuesday.
PSNI Detective Constable Kennedy said: “Damage was caused to a living room window by what would appear to be a single shot fired from a shotgun.
“A couple and their 15-year-old daughter were in the house at the time, but thankfully no one was injured as a result of this totally reckless act.”
Detectives are appealing for anyone who may have witnessed the gun attack, or who may have information that could help the investigation, to contact them on 101.
