A family of four escaped injury after a petrol bomb was thrown at their Killyleagh, Co Down, home last night.
No one was hurt, but a window was broken and wall was damaged at 11.45pm.
Police are investigating a possible link with another petrol bombing that damaged a car in nearby Osborne Drive, Shrigley, at around midnight.
