Half of a three roomed flat on the third floor of a seven storey building was destroyed by fire. One person left the flat and was treated on scene by London Ambulance Service for smoke inhalation. Around 60 residents evacuated from the block of flats before the Brigade arrived.
The Brigade was called at 2230 and the fire was under control by 2253. Fire crews from Croydon, Norbury, Woodside, Mitcham, Wallington, Wimbledon and Beckenham fire stations were in attendance.
The cause of the fire is under investigation.
