Debris smoulders outside the factory on Sunday morning
A number of people were moved from their homes for a time on Saturday night due to a fire in south Belfast.
Firefighters were worried the fire in a derelict factory at Maldon Street off the Donegal Road would spread to neighbouring properties.
At the height of the blaze six fire engines, along with other support appliances, fought it.
Martin McDonald of the fire service said it was difficult because of the dangerous condition of the factory.
"It was difficult because of the fact that the main fire was inside a derelict factory which had suffered fires on previous occasions, so the structure was damaged inside the factory.
"So basically we had to fight the fire from outside until the main bulk of the fire was extinguished," he said.
