The man cleared of murdering Trayvon Martin, an unarmed black teenager, in a case that prompted a national debate about racism in the United States, has been arrested on suspicion of domestic violence.
George Zimmerman has had a string of run-ins with the law since being acquitted in controversial circumstances for the 2013 shooting.
He was detained on Friday in Florida for aggravated violence with a weapon, according to Seminole County Sheriff's Office in Forida, and appeared in court a day later.
Local media quoted Don West, Mr Zimmerman's attorney, saying his client had thrown a wine bottle during the incident.
