Firefighters battled a blaze on Saturday.
It happened around 3 a.m. at the Cricket Wireless store near Flamingo Road and Boulder Highway.
Clark County Fire Department crews say it appears to be an electrical fire.
There didn't appear to be any damage inside, but the roof of the store was damaged. There's no estimate on how much the damage will cost.
There is a vacant store next door that sustained minor damages. There was nobody inside the wireless store when the blaze broke out.
Fire crews will continue to investigate.
