LONGMONT (AP) - A pile of railroad ties has caught fire in Longmont, disrupting electrical power and traffic signals and sending a cloud of thick smoke into the sky.
No injuries were reported from the fire, which started Wednesday night, but police closed a nearby street in part because of a potential health hazard from the smoke.
The Longmont Times-Call reports investigators believe the fire was intentionally set. Police were searching for two people seen running from the area but weren't sure if they were involved in the fire.
The flames melted power lines, and the city-owned electric utility says about 300 customers lost power for an hour. Several traffic lights were knocked out.
The fire was near a sewage treatment plant. Police said they didn't believe the plant wasn't in danger.
