By City News Service Judge holding gavel in courtroom LOS ANGELES (CNS) - A Black social worker is suing the Los Angeles County Department of Children and Family Services, alleging a supervisor made a racially insensitive remark about jewelry she was wearing. “Why do you wear so many bracelets? Is it because you want to become a slave again?'' Mark Wing C. Cheung, a DCFS assistant regional administrator and co-defendant in the suit, allegedly asked plaintiff Jennifer Jackson Warren. Warren seeks unspecified damages in the suit filed Thursday. A DCFS representative did not immediately reply to a request for comment.
