Zimmerman's girlfriend, Samantha Scheibe, alleged that he had aimed a shotgun in her direction and choked her.
"You just broke my glass table. You just broke my sunglasses and you put your gun in my freaking face and told me to get the (expletive) out," Scheibe can be heard saying in the 911 call.
But Schiebe has walked back her allegations in a sworn statement, asking a Florida judge to drop charges against Zimmerman.
"I want to be with George," the 27-year-old says in the December 6 affidavit.
She also says police "misinterpreted" her remarks at the time of the arrest.
"When I was being questioned by police I felt very intimidated," she says. "I believe that the police misinterpreted me and that I may have misspoken about certain facts in my statement to police."
Scheibe said Zimmerman "never pointed a gun at or toward my face in a threatening manner."
Zimmerman had a similar run in with the law since his acquittal in the Martin case.
In September, Zimmerman's estranged wife, Shellie Zimmerman, called 911 when he allegedly punched her father in the face. No charges were filed.
