FLATS were evacuated after a fire at Gateway Plaza on Thursday evening.
The fire started in the basement of the complex, beneath a former NHS office building.
Fire crews searched the 10-storey complex and ventilated an office building and underground car park.
Some of the 200 flats were evacuated, but only one female casualty was given oxygen for slight smoke inhalation.
Four fire engines - from Barnsley, Tankersley and Cudworth fire stations - attended the fire at about 6.10pm and left the scene just before 8pm.
A fire cause investigation concluded the fire was started deliberately.
