Firefighters have issued a smoke alarm reminder after a fire at a sports pavillion in Poplar High Street, Poplar.
There was no alarm system in the property and the Brigade were called after a member of staff saw smoke outside on the bowling green.
A London Fire Brigade spokesperson said: "Incidents like this show how important it is to have a working fire alarm in homes but also businesses. That means that if there's a fire, there is a way for that fire to be easily detected and occupants can be warned easily.”
Half of the roof was damaged by fire and the remainder of the property sustained smoke damage. Around 30 people left the building before the arrival of the Brigade.
The Brigade was called at 1815 and the fire was under control at 1920. Four fire engines and 21 firefighters and officers from Poplar and Millwall fire stations attended the scene.
The cause of the fire is under investigation.
