George Zimmerman is no longer being detained by police after a confrontation with his estranged wife at her father’s home, according to multiple media reports.

Shellie Zimmerman and her father both signed paperwork declining to press charges, The Orlando Sentinel reported, after she told police George Zimmerman threatened her family with a gun and assaulted her father Monday, police confirmed to TheBlaze.

Lake Mary Police Chief Steve Bracknell told TheBlaze they received a call at 2:10 p.m. Monday from Shellie Zimmerman saying she was visiting her father at her father’s home when George Zimmerman threatened the family with a gun. Shellie Zimmerman filed for divorce last week.

“She advised that he battered her father and was being aggressive,” Bracknell said, noting that it was only one side of the story.

Bracknell said police arrived on the scene and placed George Zimmerman in “investigative detention” while they could ascertain what happened. He was not under arrest, but was still “sitting in a police car” an hour after the initial call, Bracknell said.

NBC News reported after the confrontation was over that police had taken Zimmerman’s gun.

Shellie Zimmerman told a 911 dispatcher that George Zimmerman punched her father in the nose and then was sitting in his truck with his hand on his gun, according to audio posted by WKMG.

“He’s in his car and he continually has his hand on his gun and he keeps saying ‘step closer,’ he’s just threatening all of us with his firearm,” Shellie Zimmerman said.

“Step closer and what?” the dispatcher asked.

“And he’s going to shoot us,” Shellie Zimmerman said. “He punched my dad in the nose, my dad has a mark on his face, I saw his glasses were on the floor. He accosted my father and then took my iPad out of my hands and smashed it and cut it with a pocket knife…I don’t know what he’s capable of, I’m really, really scared.”

After several moments, Shellie Zimmerman said police had arrived and had their “guns drawn” on Zimmerman in his car.

“They’re telling his bodyguard to get out of the way,” she said.

Then, a couple of minutes later, Shellie Zimmerman repeated to someone with her, “Someone’s in there?…There’s a woman in there. Oh my God.”

In an interview with ABC aired after the divorce filing, Shellie Zimmerman called her husband “selfish,” said he had been verbally abusive toward her, and that he felt “invincible” after a jury acquitted him of murder in the shooting death of 17-year-old Trayvon Martin. She also said he had been making “reckless decisions.”

George Zimmerman has been pulled over twice for speeding since his acquittal; police ticketed him in Lake Mary last week, and left him off with a warning in Forney, Texas, two weeks after the verdict.

Shellie Zimmerman pleaded guilty last month to a misdemeanor perjury charge after prosecutors said she lied to a judge about how much money she and her husband had to pay for his defense after he was arrested last year. She was sentenced to a year of probation and 100 hours of community service.

After news of Monday’s incident surfaced, Zimmerman’s brother, Robert Zimmerman Jr., tweeted: “We’ve learned from GZ case not to “jump to conclusions”, to wait for facts, & to avoid speculation. “News” is a business – not your friend.”
