 The protection rackets proved to be extremely profitable and drew attention from other gangs such as Billy Kimber's Birmingham Boys.Sabini managed to defeat Kimber and outmaneuver another gang leader Edward Emmanuel forcing them to desert their protection rackets at the racecourses.In 1929, the Jockey Club and the Bookmakers' Protection Association took measures to prevent Sabini from controlling the best pitches and his other affairs on the racecourses came under attack from the police.
