PORTLAND -- Investigators announced Monday that a five-alarm fire at a Northeast Portland apartment complex last week was the result of arson.
The fire started in an apartment complex under construction on Northeast Martin Luther King, Jr. Boulevard around 4 a.m. The five-story building collapsed during the blaze.
The fire caused an estimated $5 million in damage, but Portland Fire & Rescue Lt. Rich Chatman said it could have been much worse.
"At 4 o'clock in the morning, in a very residential area, there were a lot of people at home sleeping," he said. "So the fact that a fire that size was in that densely populated an area, we were very fortunate not to have any death or injuries."
Every available Portland firefighter and piece of equipment responded to the fire, including more than 120 firefighters.
Portland Fire & Rescue was working with the ATF to find the party responsible for the blaze. A $2,500 reward was offered for information that leads to an arrest in the case. Call 1-888-ATF-FIRE to report any tips.
