Firefighters were called out to the same location twice in one night to tackle an arson on a double decker bus.
Crews from southern station extinguished the first blaze, which had been started deliberately on the back seat of a bus in Hillsborough Road, Glen Parva, at about 2.20am today.
The fire service received a second call at about 3am to the same spot – near the Glen Pub – and found flammable materials had been used to start another fire on board the vehicle.
They used hose reel jets to put out the flames and left the scene a short time later.
A spokesman said there was a small amount of damage to the bus's seats.
