Police doubt credibility of bomb threat at high school in Fresno

Fresno police are doubting the credibility of a bomb threat made at Edison High School on Thursday.

Police Lt. Mark Hudson said there was graffiti that suggested a bomb was on campus.

He said police cleared an area of the campus to ensure nothing was there.

The threat was spotted about 9 a.m. in a campus bathroom, said Jessica Baird, Fresno Unified School District spokeswoman.

Students were not taken out of class, and police remained on campus throughout the morning as a safety precaution, she said.
