LAS VEGAS (KLAS) — The Boulder City Fire Department was working Friday to extinguish two house fires caused when a backyard pole ignited and collapsed, according to a social media post by the city’s police department.

Police said in the post that a backyard pole caught fire, burned down and dropped on a transformer.

Some 25 to 30 customers lost power because of the downed transformer, the post said.

The post asked people to avoid an area of Wyoming Street from Northridge to Cayuga.
