Walnut Creek, Calif. ? A man suspected in more than 30 bank robberies across the country was arrested after cyclists recognized his $3,000 custom-made racing bike on an Internet “wanted” poster.

FBI agents arrested Thomas Justice, 31, at his parents’ house Tuesday in a Chicago suburb on suspicion of robbing a Walnut Creek bank, said Walnut Creek Police Lt. Loren Cattolico.

The FBI has accused Justice of robbing at least seven Bay Area banks in the past year and also is investigating him in connection with robberies in San Diego and Milwaukee. Chicago authorities think he’s behind another 10 robberies in that city’s northwest suburbs.

Illinois authorities say the suspect repeatedly eluded them by stripping down from street clothes into cycling gear, then pedaling away.

Authorities gained a clue in March after a bank robbery in Walnut Creek. The suspect escaped but left behind his racing bicycle. A bicycle company posted a “wanted flier” with photos of the suspect and the bike. Two people then gave police Justice’s name.
