Police have initiated an arson investigation in connection with a two-alarm fire that damaged a home in Ewa Beach.

Shortly after 10:20 p.m. Monday, nine units with 31 firefighters responded to the fire at 91-214 Makalea St. When they arrived, firefighters observed smoke emanating from the structure, said Honolulu Fire Department spokesman Capt. David Jenkins.

When they entered the home, they discovered a fire in the master bedroom. Firefighters brought the fire under control at 10:56 p.m. and extinguished it at 11:08 p.m.

No one was home at the time.

Jenkins said Honolulu fire investigators were at the scene Tuesday. The cause of the fire and a damage estimate have yet to be determined.

According to a preliminary police investigation, an unknown male entered the home sometime between 8:16 and 8:29 p.m. and started a fire before he fled.

The man was wearing a dark-colored ski mask, light-colored jacket and pants, and slippers at the time of the fire.
