George Zimmerman threatened wife, her dad, she tells 911

(CNN) -- George Zimmerman was detained after his estranged wife told 911 that he had threatened her and her father with a weapon, Lake Mary, Florida, police told reporters Monday.
Zimmerman was being cooperative, Lake Mary police spokesman Zach Hudson said.
Shellie Zimmerman, who filed for divorce last week, called 911 just after 2 p.m. ET, Lake Mary Police Chief Steve Bracknell said. She told police that George Zimmerman was inside the house with a gun and was threatening her family, the chief said.
Bracknell added that Shellie Zimmerman claimed her husband "battered her father," according to the call report. It was unclear if he received medical treatment from first responders from the fire department.
George Zimmerman's attorney, Mark O'Mara, told CNN, "There was heightened emotion, and a disagreement took place."
O'Mara said his client wasn't taken to police headquarters but was being questioned near the house, which is owned by his father-in-law, David Bryant Dean.
Bracknell said that as of 4 p.m., Shellie Zimmerman had yet to give a sworn statement to police, but she had spoken with her attorney.
The incident comes two months after Zimmerman, a neighborhood watch volunteer, was found not guilty of murder in the shooting death of Trayvon Martin in Sanford, Florida.
Hudson said earlier that police are following procedure by placing Zimmerman in investigative detention.
"Anytime we have anybody suspected of doing anything, we place them in investigative detention until a complete investigation has been done," Hudson said.
George's brother, Robert, tweeted after his brother's detention that the public shouldn't "jump to conclusions."
Shellie Zimmerman filed for divorce last week in Seminole County, her attorney told CNN at the time.
That filing came after she pleaded guilty to perjury on August 28 for lying about the state of the couple's finances during a bond hearing in April 2012. She had claimed she and her husband were broke, when in reality they had collected about $135,000 in donations.
Since his acquittal on July 13, George Zimmerman has been in the headlines several times. In late July, he reportedly helped a family escape from an overturned SUV. A report from the Seminole County Sheriff's Office confirmed his involvement.
More recently, Zimmerman has been pulled over in traffic twice. The first time, he was given a verbal warning for a traffic violation in Texas and reportedly told officers he had a firearm in his glove compartment. The second time was in Florida last week, when he was issued a $256 ticket for speeding.
