A fire at a Waikiki hotel was intentionally set, according to a Honolulu fire spokesman.

This is third fire that was intentionally set at a Waikiki hotel this week.

Firefighters responded to a small fire in the hallway on the 28th floor of the Grand Waikikian by Hilton on Ala Moana Boulevard at about 8:44 p.m Tuesday night.

The blaze activated a fire alarm system, prompting hotel security to evacuate occupants on the affected floor.

Honolulu Fire spokesman Capt. Scot Seguirant said hotel security quickly extinguished the fire using a portable fire extinguisher.

Damage was estimated at $10,000.

The fire was consistent with two previous fires intentionally set in Waikiki hotels this week, he said.

On Sunday, an intentionally set fire at the Alohilani Resort was quickly extinguished, Seguirant said.

A Waikiki hotel fire Monday night at the Waikiki Beachcomber by Outrigger forced the evacuation of the building and was intentionally set, the Honolulu Fire Department investigators determined.

The HFD has referred the three fires to police for further investigation.

They also estimate damage to Waikiki Beachcomber at $1,765,650.

The fire at the Waikiki Beachcomber broke out near a storage room on the 14th floor just before 8:36 p.m. A fire alarm and sprinkler system were activated, which alerted occupants and kept the fire from spreading. The fire was brought under control at 9:08 p.m. and was extinguished at 9:13 p.m.

One unit on the 14th floor requested assistance to evacuate, but they were directed to shelter in place.

However, the building was evacuated by firefighters due to smoke.

There were no injuries in the three fires.
