George Zimmerman was charged with assault Monday after his girlfriend called deputies to the home where they were living and claimed he pointed a shotgun at her during an argument, authorities said.

The girlfriend, Samantha Scheibe, called 911 in the early afternoon to say that Zimmerman had smashed a glass table, threatened her with the shotgun and ultimately pushed her out of the house, according to an arrest report. After pushing her out, Zimmerman barricaded the door with furniture and refused to leave, saying that he would talk to police by phone, authorities said.

The arrest was the latest legal problem for Zimmerman since he was acquitted of criminal charges earlier this year in the fatal shooting of Trayvon Martin, an unarmed black teen. The case, and claims that the killing was racially motivated, stoked a discussion on racial profiling across the country.

“You point your gun at my fricking face,” Scheibe is heard telling Zimmerman on a 911 call. “Get out of my house. Do not push me out of my house. Please get out of my house.”

Seconds later, she told the dispatcher, “You kidding me? He pushed me out of my house and locked me out. … He knows how to do this. He knows how to play this game.”

Moments later, Zimmerman called 911 from inside the barricaded house to tell his side of the story.

“I have a girlfriend, who for lack of a better word, has gone crazy on me,” Zimmerman said.

Zimmerman then said he never pulled a gun on his girlfriend, and that it was Scheibe who smashed a table at the home they shared. He also told the dispatcher that Scheibe was pregnant with their child and that she had decided she would raise the child on her own. When Zimmerman started to leave, “she got mad,” he said.

Seminole County Sheriff’s Office Deputy Chief Dennis Lemma said at a news conference that Scheibe wasn’t pregnant.

Deputies used a key provided by Scheibe to unlock the door and they were able to push through the barricade of items, Lemma said.

“She was very concerned for her own safety especially having the weapon pointed at her and then being pushed out,” he said.

Lemma said Zimmerman was compliant and unarmed when deputies came to the house.

Zimmerman was charged with domestic aggravated assault with a weapon, domestic battery and criminal mischief. His first court appearance was scheduled for this afternoon. He will be housed in a single-person cell and guards will check on him hourly, Lemma said.

Zimmerman has had other brushes with the law since his acquittal.

Zimmerman and his estranged wife were involved in a domestic dispute in September just days after Shellie Zimmerman filed divorce papers, but police later said no charges were filed against either of them because of a lack of evidence.

Zimmerman has also been pulled over three times for traffic stops since his acquittal. He was ticketed for doing 60 mph in a 45 mph zone in Lake Mary in September and was given a warning by a state trooper along Interstate 95 for having a tag cover and windows that were too darkly tinted. He was also stopped near Dallas in July and was given a warning for speeding.

In 2005, Zimmerman had to take anger management courses after he was accused of attacking an undercover officer who was trying to arrest Zimmerman’s friend.
