(AREA) -- The U.S. Marshals Service says a Michigan sex offender who made the state's "Top Ten Most Wanted" list has been arrested in Arizona. Authorities say 51-year-old Anthony Wayne Dolson pleaded guilty in 1993 to several counts of sexual contact with someone under the age of 13. They say he failed to register as a sex offender and fled. The U.S. Marshals Service in Arizona was able to track down Dolson and arrest him without incident Thursday morning. Dolson's last reported address was in Port Huron.
