A late-night fire in the Punahou area damaged two apartments in a two-story apartment building Wednesday on Alexander Street, the Hono­lulu Fire Department reported.

No one was injured but the fire displaced five residents.

The fire appeared to have started in a first-floor bedroom of a unit at the Alexander Apartments. The fire spread to a second-floor apartment, damaging a bedroom and a bathroom.

The first fire companies were dispatched to 1424 Alexander St. at 10:49 p.m. and arrived three minutes later. Firefighters reported that smoke and flames from the bottom floor had extended to the second floor.

Firefighters brought the blaze under control by 11:06 p.m. and had it extinguished by 11:45 p.m. About 35 firefighters responded.

A woman who lives in the bottom unit escaped uninjured with her two dogs. A family of two adults and two children who live in the second-floor unit also escaped uninjured. The American Red Cross responded and offered help to the displaced residents.

The fire is under investigation. No damage estimate was immediately available.
