A woman and her three children – one aged just six – have been forced to flee their home in Crumlin, Co Antrim after an arson attack.
The family were asleep when the incident occurred in the Ballydonaghy Meadows area at about 4.35am on Friday.
The 35-year-old woman was woken by a loud bang and went downstairs to see smoke and flames and broken glass at the door, which had been extensively damaged.
It was initially believed that a petrol bomb had been used, but police have since said that further examination has shown that not to be the case.
PSNI Detective Chief Inspector Dunny McCubbin said: “The woman fled from the house with her children, aged 15, 11 and 6.
“While no-one was injured during this incident, there could have been serious consequences.”
Police are appealing for anyone who saw suspicious activity in the area to contact them on 101, or to pass information anonymously via Crimestoppers on 0800 555 111.
