NANAKULI, Hawaii - The Honolulu Fire Department is investigating what caused an abandoned house in Nanakuli to catch fire two days in a row.

At least a dozen fire trucks were called to the 3-alarm structure fire at an abandoned house on Mikana Street around 3:45 a.m. Tuesday.  One man was inside the home at the time of the fire, but left the scene, according to HFD. 

The fire destroyed the abandoned home and heavily damaged a neighboring two-story home. Eight people were inside sleeping, but managed to escape, according to HFD. One person was treated on scene for burns to their arm. No other injuries were reported. The Red Cross was on scene to assist the family.

Battalion Chief Craig Uchimura says firefighters extinguished a fire at the same abandoned home Monday morning. Neighbors tell Island News the house has been abandoned for years and has been set on fire by a homeless man several times over the past few months.

The cause of the fire is under investigation.
