Citing law enforcement sources, the news outlet reported on Saturday, October 8, that the FBI never opened an investigation against the Allied actor, 52, because there was "no case."
The FBI is still working to gather the facts from the incident but the agency does not consider it an official investigation, TMZ reported.
As Us Weekly previously reported, Pitt and his estranged wife, Angelina Jolie (who filed for divorce less than a week after the incident occurred), were flying with their six children from Nice, France, to Burbank, California, on September 14. TMZ initially reported that the Fight Club actor got "verbally abusive and physical" with the kids — Maddox, 15, Pax, 12, Zahara, 11, Shiloh, 10, and 8-year-old twins Knox and Vivienne.
A source told Us that Jolie, 41, and her partner of 12 years, who allegedly was drunk, got into an argument on the flight and "Maddox stepped in to defend Angie and got in Brad's face." A second Pitt insider, however, claimed that "the abuse suggestions are inaccurate."
Another source then told Us that someone anonymously called the Department of Children and Family Services during the flight, but the agency let Pitt and Jolie go after interviewing them.
The Mr. & Mrs. Smith actress filed for divorce on September 19, citing irreconcilable differences, and requested sole custody of the kids. The former power couple have since reached a temporary custody agreement, which allows Pitt supervised visitation. He will also voluntarily take random drug and alcohol tests, his first of which came back negative.
