Part of the Singapore Marriott Tang Plaza Hotel caught fire on Tuesday morning (Mar 15).
The Singapore Civil Defence Force (SCDF) said the fire, outside the third storey roof of the hotel, was first spotted by a member of security staff around 9.10am. The staff alerted the hotel's fire command centre, which deployed its in-house fire-fighting team.
An estimated 100 people also self-evacuated from the hotel before the SCDF's arrival.
Fire fighters arrived at the scene at about 9.15am with two fire engines, two fire bikes, two Red Rhinos, one ambulance and three support vehicles, and were guided by Marriott's fire-fighting team to the location of the fire.
The flames were extinguished with one water jet and two hoses within 20 minutes, and there were no injuries, the SCDF said.
The Singapore Police Force confirmed it had investigated the incident and found the fire to have been accidental. SCDF said it was still investigating the exact cause of the fire.
At around 10.50am several SCDF officers were seen surveying the damage after the flames had been extinguished.
