According to authorities, a single vehicle collision in Armagh, Northern Ireland, claimed the lives of four people.
McGrattan said this is “an unspeakable tragedy for the families involved, and for the wider community, who will understandably struggle to comprehend such loss of life.
“A thorough and sensitive investigation is now under way and anyone with information that could assist us is asked to get in touch with the Collision Investigation Unit,” he added.
Police remain at the scene at present and the Ballynahonemore Road will be closed for most of the day.
