The incident happened the day after a Los Angeles jury ruled in favor of the golf club in a discrimination lawsuit. Former drink server, Carley Cooter, accused the club of retaliation, discrimination, harassment and wrongful termination, according to the Los Angeles Times. Three more similar cases are pending against the club.

Three large rock formations were found on the course, and a swastika was painted on a fence, club spokesman Eric W. Rose said.
