Authorities intercepted a suspicious package with explosives that was addressed to tough-talking Arizona Sheriff Joe Arpaio.
U.S. Postal Inspector Andrew Rivas in Flagstaff screened the package Thursday and realized it was suspicious enough to call the local police bomb squad and the FBI.
"We evacuated the post office, got all our employees to safety," Rivas told CNN affiliate KTVK.
The Maricopa County Sheriff's Office said Flagstaff police X-rayed the package and neutralized it Thursday night.
