Fire crews responded to a fire in downtown Spokane Tuesday night after flames sparked inside the Les Schwab Tire Center on 2nd and Browne. The fire then quickly spread to the nearby Days Inn Hotel. Fire officials said they are treating the fire as a suspicious act, but did not confirm if they were dealing with an arsonist. Investigators have been on the scene all night. Both the Days Inn Hotel and Les Schwab were evacuated. Multiple roads were also closed too. Avista crews were also on scene as the fire reached some power lines affecting the power on 2nd between Browne and Bernard. Fire officials said this was just one of several fires they have responded to in the downtown area over the past few days.
