A couple of blazes kept firefighters busy last night. In northeast Reno, residents of a home on Kate Lane were displaced by a fire that damaged their house. Reno firefighters say it appears the fire can be blamed on electrical issues,but the cause is still under investigation. Meanwhile, Truckee Meadows Fire Protection doused a chimney fire at a home on Riata Circle in south Reno, before the flames could spread to the interior of the home. No one was hurt.
