The suspect was seen driving different vehicles in separate incidents, including a silver 2016-18 Volkswagen Passat; a silver extended-cab pickup truck, possibly a GMC or Chevrolet; a red four-door sedan; and a gray BMW.
Floyd was booked on six counts of indecent exposure and one probation violation. He was being held at Los Angeles County Jail on $70,000 bail.
