The Madera County Courthouse at Bass Lake is closed and will remain closed all day.
Around four this morning, someone threw a small device through a window. That caused a fire which caused some minor damage inside the building.
Two bomb threats, including one to ksee 24, were also called in for the courthouse as well.
The building is currently under an evacuation order. A bomb sniffing dog is being used for a security sweep.
The Madera County Sheriff's Department and Cal Fire have launched an arson investigation. We do have a crew at the scene and will have much more on this story tonight.
