A fire at a house in Co Antrim has caused "substantial damage" to the property, police say.
The blaze, which happened at the front door of a house in the Larne Street area of Ballymena, was reported to the Northern Ireland Fire and Rescue Service at around 1.45am on Monday, July 11.
Firefighters extinguished the blaze, which was determined to have started from a tyre being placed against the door and set alight.
