A Honolulu firefighter was taken to a hospital after he suffered a leg injury while he and other firefighters battled a late-night fire that broke out at an auto repair shop in Makiki.

Eleven units with more than 40 firefighters responded to the blaze at a two-story commercial structure at 1084 Young St. just before 11 p.m. Thursday.

Honolulu Fire spokesman Capt. Jeffrey Roache said firefighters observed smoke and flames emanating from the second floor when they arrived.

They brought the blaze under control just after 12:50 a.m. and extinguished it at about 1:40 a.m. today.

Emergency Medical Services personnel treated one of the firefighters, 40, for a leg injury. He was taken to The Queen’s Medical Center where he was treated and released.

Residents who live in an adjacent apartment building said they evacuated their units after a neighbor alerted them of the fire. A resident who declined to give her name said she saw a lot of smoke billowing from the auto repair shop’s windows.

The cause of the fire is under investigation. A damage estimate was not immediately available.
