FRESNO, Calif. (KFSN) -- Fresno firefighters are investigating what caused a vacant home in Central Fresno to go up in flames twice this week.
Around 4 a.m. Saturday, crews were called out to Olive and Wishon Avenues.
Crews arrived to heavy smoke and say the structure is now a total loss.
It's unclear what sparked the fire.
However, on Wednesday firefighters say the vacant home was set on fire on purpose.
It also broke out around 4 a.m. and a neighbor called first responders.
Arson investigators are now working to identify any possible suspects.
If you have any information, you can call the Department's Arson Hotline at (559) 621-2767.
