A man was arrested Sunday after confessing that he started the structure fire in Chalan Piao on the same day.
Tebei Malaitau, also known as Teddy, was arrested for charges of arson and was transported to the Department of Corrections where he was booked and detained.
Police officers found Malaitau watching nearby the structure fire at the Rainbow commercial building across from the Bank of Guam Chalan Piao branch.
They interviewed the 34-year-old suspect who admitted starting the fire.
Malaitau was identified by some of the witnesses interviewed by patrol officers. The witnesses said a suspicious person was seen around the area before and after the fire started.
The suspect was described as a Palauan male in his mid-30s dressed in a dark T-shirt, light-colored short pants, and a black baseball cap.
Police, Fire, and Emergency Medical Services personnel were dispatched at about 5:11pm to the scene where they found the structure fully engulfed in fire and smoke.
The police assisted Fire and EMS staff in evacuating people from the Rainbow building and other adjacent buildings and provided a perimeter safety zone.
Seven of the nine units of the commercial building were damaged but no one was reported injured from the fire incident, which was put under control by firefighters at about 7:02pm.
Other agencies that provided assistance during Sunday's fire incident were the American Red Cross-NMI Chapter, Commonwealth Utilities Corp., Department of Homeland Security, and the Division of Environmental Quality.
The Department of Public Safety said investigation on the case is ongoing.
