The Northern Ireland transport company, Translink, says the cost of the damage caused in a petrol bomb attack on a bus depot in Co Antrim will be at least £200,000.
Four buses were destroyed in the incident at around 5am this morning, and a tyre store was also burnt out.
Two other buses were damaged when the petrol bombs were thrown over a security fence at the depot in Whiteabbey, near north Belfast.
Quick-thinking staff on duty prevented further losses by driving vechicles away from the fire.
Several houses adjoining the depot had to be evacuated while three fire crews dealt with the blaze.
The PSNI has launched an investigation into who was behind the arson attack.
