Police have initiated an arson investigation after the Honolulu Fire Department determined a residential fire in Kapalama was intentionally set.

At 12:46 p.m. Tuesday, firefighters responded to a two-alarm fire at 1218 Alani Street. Police said the fire broke out within the first level of the two-story home while two women were at home.

One of the two residents, 20, who was inside the first level climbed out of a window.

Honolulu Fire Capt. David Jenkins said both residents were able to escape without injury.

Firefighters brought the fire under control shortly before 1 p.m. and extinguished it by 1:12 p.m.

Damage was estimated at $6,000 to the structure and its contents.
