George Zimmerman in police custody after gun-related incident

George Zimmerman, the man who shot and killed unarmed teenager Trayvon Martin during an altercation in Florida almost two years ago, has been placed in police custody for reportedly threatening his wife with a firearm.

Central Florida’s WKMG News reports that Zimmerman was apprehended on Monday after police were dispatched to a Lake Mary, FL home to respond to a call involving an alleged threat. The Associated Press says that home belongs to Zimmerman’s father-in-law, and authorities were told that the former neighborhood watch volunteer threatened his wife with a gun.

Speaking to CNN, police said Zimmerman was in “investigative custody” following the incident.

Lake Mary police spokesman Zach Hudson told WKMG that officers are "trying to determine what exactly happened,” but preliminary reports suggest law enforcement apprehended Zimmerman after being called to investigate an altercation between two people. The network says the incident involved a threat and a gun, but failed to elaborate further.

The news comes only days after Shellie Zimmerman filed for divorce, and less than two months after a jury acquitted her husband of second-degree murder and manslaughter charges brought by officials after the February 2012 death of Martin.
