George Zimmerman George Zimmerman

George Zimmerman was taken into police custody after a "domestic altercation"Monday in Lake Mary, Fla., CNN reports. His wife Shellie, who filed for divorce last week, called 911, according to CNN.

Zimmerman had not been arrested or charged with anything as of Monday afternoon, but was being held in "investigative detention" while authorities looked into the incident, which involved Shellie Zimmerman and her father, a police spokesperson told CNN.

In July, Zimmerman was found not guilty of murder and manslaughter after fatally shooting teenager Trayvon Martin in 2012. This isn't Zimmerman's first run-in with the law since he was acquitted; he's been pulled over twice for speeding in Florida, and last month Shellie Zimmerman pleaded guilty to perjury for lying about their financial situation after her husband's arrest in 2012.
