When the Polk County Sheriff's Office arrested David Hernandez Jr., 56, on Saturday, he was working at the county fair in Fertile, according to authorities.
He claimed to be Joe Hernandez, 50, a worker for a Texas firm that subcontracted with rider operators Murphy Brothers, according to investigator Nathan Rasch with the sheriff's office.
Authorities initially thought he might have been an illegal alien even though Hernandez said he's an American Indian. With help from U.S. Customs and Border Protection, who checked the suspect's fingerprints against a national database, authorities concluded Hernandez is a U.S. Citizen.
The identity check, though, confirmed that he had a warrant for his arrest from Austin, Texas and should be considered armed and dangerous.
Deputies arrested him without incident.

Rasch said Monday that he's still trying to figure out Hernandez's criminal past because he was playing phone tag with Texas authorities all day. The arrest warrant, he said, only stated that Hernandez had a parole warrant from a previous homicide conviction but not what kind of homicide it was.
David Hernandez Jr. does not have a middle name on record. The record did say that his parole was revoked in 1992, though Rasch said he's not sure if the suspect has been on the run that long or not.
The sheriff's office arrested Hernandez only after receiving a complaint of sexual abuse from the fair Friday. Deputies found him the next day at 7 p.m.
The case is still under investigation, and Rasch said he couldn't reveal any details. Authorities have not filed charges, he said, but if they did, Hernandez would have to face them here before Texas authorities get him.
Rasch said he expects an extradition hearing for Hernandez this week.
He's being held at the Tri-County Corrections Center in Crookston.
