PHOENIX (AP) — A man has pleaded guilty to charges of trying to stalk Maricopa County Sheriff Joe Arpaio last year.
Maricopa County Superior Court officials say 43-year-old Ruben Pena Jr. pleaded guilty Thursday to one count of attempted stalking and one count of a hoax.
His sentencing is scheduled for June 2.
Authorities say Pena went to the MCSO headquarters building on Dec. 8, requesting to speak with the sheriff regarding an identification issue.
They say Pena's request wasn't completed in a timely manner and he allegedly left behind a threatening letter.
Sheriff's investigators determined Pena had been in the building several other times making threatening statements against Arpaio.
Authorities say Pena also allegedly wrote two letters a week later that prompted a bomb sweep of a downtown Phoenix hotel.
