TAMPA — Hillsborough County is banning employees from participating in certain motorcycle clubs after a firefighter associated with the Outlaws MC was accused of taking part in a bar fight in Key West.

In a memo Friday, County Administrator Mike Merrill outlined a new policy effective immediately barring membership in groups or gangs considered criminal organizations by the state or federal government.

Involvement in these organizations “will not be tolerated as these affiliations are contrary to the mission of public service,” Merrill wrote. “This directive is a reminder of our continuing obligation to represent all the citizens of Hillsborough County.”

The list of banned organizations is guided by the 2015 FBI National Gang Report and it includes the Outlaws, as well as Crips, Bloods, Almighty Latin King and Queen Nation, Hells Angels Motorcycle Club and the Pagans.

Violating the rule can result in termination of employment.

The announcement comes after an arrest warrant was issued in Key West for Clinton Neal Walker, a Hillsborough County firefighter and suspected member of the Outlaws MC. He is accused of taking part in a September bar fight involving as many as 15 Outlaws members.

According to the FBI, the Outlaws use their motorcycle clubs as conduits for crime, including trafficking in weapons and drugs.
