One of the 170 bikers arrested after Sunday’s deadly shootout between rival biker gangs in Waco, Texas, is a former San Antonio Police Department detective. Martin Lewis, 62, retired in 2004 after 32 years with the SAPD and is reportedly a member of the Bandidos Motorcycle Club.

From the San Antonio News-Express:

Pictures posted to Lewis’ Facebook identify him as member of the Patrons Motorcylce Club, however, other images show him wearing different red and gold club patches identifying him as a supporter of the Bandidos Motorcycle Club, and that show he is based in San Antonio.

Other photos show Lewis posing with high-ranking members of the Bandidos, including the Austin chapter president.

The Bandidos are considered an “outlaw motorcycle gang” by the FBI and were one of the gangs allegedly involved in Sunday’s shootout.

Lewis has been charged with engaging in organized criminal activity and is being held on $1 million bond.
