A 57-year-old 'Aiea resident was able to extinguish a garage fire at his Ali'ipoe Drive home early today which fire investigators determined was intentionally set.

Police are investigating the case as a first-degree arson.

The resident told police he was awakened at 12:55 a.m. by the sound of a vehicle driving off and went out to investigate because the motion-sensor light was on.

The resident saw flames coming from his garage but was able to put out the fire with a garden hose, police said.

The five occupants of the home were not injured. Police have made no arrests.
