HENDERSON, Nev. -- Fire investigators are looking into what caused a fire at a post office Sunday afternoon.
Clark County Fire Department Deputy Chief Erik Newman said nobody was injured in the two-alarm fire reported about 2:30 p.m. on Sunday at the Silverado Station post office at the intersection of Pebble and Bermuda roads.
When crews arrived, they saw huge plumes of black smoke coming from the roof. Crews discovered that the fire was coming from a portable toilet on the roof.
Newman says crews cut into the roof as part of their firefighting efforts, and water and debris from the melted toilet seeped into the building.
U.S. Postal Service spokesman David Rupert says no mail was damaged; however, the post office will be closed indefinitely for cleanup and repairs.
He says mail delivery will continue, and a mobile post office in the parking lot will provide some services. A full-service window is available at the main post office on Sunset Way.
Investigators are treating it as suspicious. No injuries were reported. Officials think crews were doing some sort of work up there earlier in the week and had left for the 4th of July holiday weekend.
