George Zimmerman is being detained by police after allegedly threatening his wife's father with a gun.

It happened in Lake Mary, Florida this afternoon. Law enforcement sources tell TMZ ... Zimmerman's wife, Shellie, called 911 and said her dad and George had gotten into a big argument and George had his hand on a gun.

We're told cops are at The Zimmerman house right now and have George detained for questioning. There appears to be no one injured.

Shellie filed for divorce last week. She went on TV and trashed George, saying he was making "reckless decisions."

12:25 PM PT -- Lake Mary Police Chief Steve Bracknell tells TMZ, Shellie was visiting her father this afternoon when George arrived and became aggressive. The chief says George allegedly threatened Shellie and her family, and had his hand on his gun. Shellie told police George then hit her dad.

8 officers are currently on the scene. George is currently being detained and has NOT been arrested.

(CNN) -- No charges will be filed against George Zimmerman after an alleged altercation with his estranged wife and her father, Lake Mary, Florida, Police Chief Steve Bracknell said Monday.
"Shellie Zimmerman has declined prosecution (after consulting with her attorney)," Bracknell said.

Her attorney has obviously managed to find an angle out of this and is using it.

In Fla there is a seperate court for Domestic Vviolence with its own rules. More than 50% of the time the battered spouse diecides not to press charges.

Leave the poor man alone, yeah he travels with a gun because the liberal media made him a target. I like how when this story first came out it was zimmerman threatens wife. Than by the end of the night it was Zimmerman assaulted his father in law. Than turned into Zimmerman broke his nose. WILL YOU LIBERALS LET IT BE. First off zimmerman didnt assault his FIL. If he did hed be put in cuffs no doubt about it. In florida you cant call the cops on your husband for beating you or someone else in the house, and than when the cops get their be like oh nevermind. The reason they didnt arrest zimmerman on assualt charges was because their was no sign that he laid a finger on anyone. Sure the guy has probably gone off the deep end a little but do you blame him? If he was sitting in his truck with a gun telling his wife to come closer or whatever than this should be looked at a domestic violence thing. Not the whole "OMG YOU SEE THIS MONSTER IS STILL ROAMING THE STREETS WITH A GUN, KILLING A BLACK BOY JUST BUYING SKITTLES WASNT ENOUGH, NOW HES GONNA KILL HIS FAMILY" thing a rest. The media made him out to be a monster, Hes a dumbass, yes, but a danger to society no. Im sure this isnt the first be fight him and wife have gotten into since February 26th, 2012.

and DonTomasso let me explain it to you, If Husband hits wife, wife calls police, and police show up and wife is bleeding, even if she begs the cops not to arrest husband they will. Thats FACT in Florida. Now the wife may not cooperate with the d.a.'s, hence will make them drop the case, but for initial arrest if their is sign of abuse the perpatrator will go to jail. So Zimmerman is not kicking his wife and fil's ass and their to scared to press charges because the minute he actually does and they report it hell be arrested. and NO their is not a separate court for domestic violence cases, they all get handled at the municipal, county court where all other traffic infractions and misdemeanors are heard, barring dui's and criminal traffic which are generally held at the circut court, so all you northern libs that think florida is some state where everything goes and nobody has to answer for their crimes than STOP FUCKING MOVING HERE WHEN YOU GET OLD AND DRIVING SLOW AS FUCK AND DRIVING UP THE HOME VALUES!

This creep (or worse) is like O.J. Simpson. Once he got away with murdering Martin, he has done a number of things that got him in trouble, and he will continue to do so. He thinks he is above the law. Like O.J. sooner or later it is going to catch up to him and he will find himself behind bars.

George Zimmerman raped his little cousin, fought the cops, and killed an unarmed teen

on top of that he attacks his father in law and threatens his wife with a gun

I think it's safe to say that Zimmerman might be a danger to society

In addition, DT's credibility with me is just fine (except when he disagrees with me).

I've only disagreed with you a few times, and that was only when you were in error

You both suck .
