The fire originated in a True Corporation customer service shop on the 4th floor of the building.
The blaze generated such a massive amount of smoke that firefighters had to wear protection suits with self-contained breathing apparatus. After dousing the flames, the firefighters deployed ventilation fans for about an hour to suck out the smoke from the building.
Officials said the situation was under control, but they nevertheless closed the area to the public for safety reasons.
Officials are investigating the scene to learn the cause of the fire and estimate the damage.
