A second fire broke out at Wisma Jakel in Section 7, Shah Alam, early today, this time affecting the curtain store room at the premises.
Selangor Fire and Rescue Department (JBPM) director Norazam Khamis said the department received a distress call at 12.40am, following which 43 firemen were mobilised to the scene.
He said they managed to keep the fire from spreading at 1.45am.
"The fire was completely doused at 3.07am and overhaul work is in progress. There were no casualties," he said in a statement.
The first fire broke out at the five-storey Wisma Jakel building two days ago. It was believed to have started at about 7am.
Selangor JBPM has mobilised its K9 tracker dog unit to the site to conduct forensic work and determine the cause of the incident.
