(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.
