PORTLAND -- Firefighters battled a five-alarm blaze in Northeast Portland that destroyed an apartment building and forced neighborhood evacuations early Thursday, authorities said.
The fire started in an apartment complex under construction near the intersection of MLK and NE Monroe around 4 a.m. A five-story building collapsed in the fire but no firefighters were hurt.
As of 6:30 a.m., the fire was contained and firefighters continued to monitor hot spots.
Firefighters also worked to make sure the flames did not spread to surrounding homes. Two adjacent homes sustained slight damage and neighbors were evacuated.
Authorities cut off power in a 4-block radius around the fire scene as a precaution. TriMet buses were also rerouted around the fire scene.
The Monroe Apartments include 46 rental units which were almost ready for tenants to move into, authorities said.
An arson investigator was at the scene Thursday.
A five-alarm fire is that largest call-out for Portland firefighters.
