SANTA ANA, Calif. (AP) — Posing as debt collectors, undercover federal agents headed to a Los Angeles County firehouse in 2011 to meet with a man suspected of illegally moving millions of dollars through an offshore sports gambling enterprise.

The man was a fire captain stationed in the scandal-plagued city of Bell, and authorities said he appeared to be at least partly operating his piece of the Costa Rica-based online sportsbook on duty.
