Washington State University investigates unsubstantiated bomb threat

A bomb threat was phoned into Washington State University late Thursday afternoon, but police do not believe it was credible.

The person claimed to have placed several explosive devices on the Pullman campus but was not specific, according to a WSU news release. Several buildings were searched “out of an abundance of caution,” but nothing was found, the university said.

The threat is being investigated by state and federal law enforcement.
