The Arizona Attorney General's Office said William J. Joachim, 35, was arrested on four felony charges of theft, fraud schemes, aggravated taking the identity of another and misconduct involving weapons.
Two other men were arrested in the case and booked into the Maricopa County jail on forgery charges.
Arizona authorities received information from the NFL last month that Favre's credit card account had been compromised and unauthorized transactions were made in Maricopa County.
Green Bay Packers security chief Jerry Parins told the Green Bay Press Gazette that it is still unclear how Joachim ended up with the three-time NFL MVP's information, but it was purchases of beer and pizza — 30 or 40 times — that first drew Favre's scrutiny.
Parins said Favre's agent, Bus Cook, approached the team's security staff with the suspicious credit card charges. Parins' people got in touch with folks from the league in Green Bay, who called their counterparts in Arizona.
League officials in Phoenix, where the purchases had occurred, reported them to local authorities.
The charges totaled more than $10,000, according to authorities.
