Las Vegas firefighters responded to a fire in a vacant downtown apartment building Thursday morning.
Just after 8:30 a.m., units arrived at the two-story building at 223 N. Ninth St. Heavy smoke was visible upon arrival, said fire spokesman Tim Szymanski.
An extra fire truck was requested. Firefighters went into the building at 8:45 a.m., Szymanski said, where they found a mattress on fire in an upstairs unit.
The fire was confined to that unit and knocked down by 9 a.m.
The cause of the fire was under investigation. A preliminary investigation showed the building is sometimes used by homeless people, Szymanski said. Investigators found evidence of previous small fires in the building a well.
There were no reported injuries. Damage was estimated at $10,000.
