An investigation is underway after a late night fire damaged ten apartments in Reno.

The blaze broke out at an apartment complex in the area of Plumas Street and Salem Place at around 11:30 p.m.Tuesday.

Upon arrival, firefighters say the fire was on the second floor but quickly spread to the third floor. 

Reno police helped evacuate residents from all three floors of the complex and closed roads in that area. 

Fire crews say one man was transported to Renown Regional Medical Center suffering from burns and smoke inhalation. Four other residents and two Reno Police officers were treated for minor smoke inhalation and released on scene. 

Crews say two apartments were heavily damaged by fire and eight others are unlivable due to smoke and/or water damage. 

Fire crews say at least 15 residents were displaced.
