Police in a central Florida town say they are investigating an incident involving George Zimmerman after his estranged wife reported that he was threatening her and her father with a gun.
Shellie Zimmerman filed for divorce last week. CNN quotes police as saying that Zimmerman is in "investigative custody."
Lake Mary Police Chief Steve Bracknell told the Associated Press that Shellie Zimmerman called police shortly after 2 p.m. on Monday.
Later Monday afternoon, Bracknell said Zimmerman's wife won't press charges even though she said he threatened her with a gun.
Bracknell says Zimmerman hasn't been arrested and officers are at the house trying to determine what happened. "We've only heard one side of the story so far," Bracknell said.
Orlando TV station WKMG reports that Shellie Zimmerman's parents, David and Machelle Dean, live at the home.
WKMG's SKY 6 helicopter of the scene shows at least a half-dozen police squad cars outside the house.
In the divorce petition, Shellie Zimmerman says she and her husband separated a month after Zimmerman, who is Hispanic, was acquitted of any crime for fatally shooting black teenager Trayvon Martin last July.
The verdict sparked protests across the nation. Zimmerman has been pulled over at least twice for speeding since his acquittal.
