PHOENIX (AP) - Federal investigators say an Oklahoma man is in custody after mailing a package with explosives to Maricopa County Sheriff Joe Arpaio last year.
U.S. Postal Service officials said Tuesday that 55-year-old Gregory Lynn Shrader is accused of sending the package addressed to the sheriff.
Investigators say the package was discovered April 11 in a Postal Service collection box unit in northern Arizona.
Authorities originally said the package appeared to contain an improvised explosive device that could have led to serious injuries or death if it was opened. But investigators later determined the device was inoperable.
Shrader was arrested last Thursday after FBI agents and postal inspectors executed a search warrant at his home in Jay, Okla.
The allegations against him are outlined in a nine-page criminal complaint.
