As Rare previously reported, Brad Pitt was under investigation by the Los Angeles County Department of Children and Families and the LAPD for alleged verbal and physical abuse against the six children he shares with actress Angelina Jolie.

The investigation began after Pitt had an outburst on a private plane; he supposedly became belligerent, yelled at and got “physical” with his family.

The investigation has been handed over to the FBI, who maintain that an anonymous tip came in to DCFS after the plane incident.

“The FBI is continuing to gather facts and will evaluate whether an investigation at the federal level will be pursued,” the FBI said in a statement.

However a source came forward on Friday to tell news outlets that Pitt did not physically abuse his son Maddox during the mid-flight argument with Jolie.

The source opened up to PEOPLE  and claimed that Pitt “was drunk, and there was an argument between him and Angelina.” The source added that “there was a parent-child argument which was not handled in the right way and escalated more than it should have.”

The source claims that the 52-year-old actor did not harm his son. “He is emphatic that it did not reach the level of physical abuse, that no one was physically harmed. He did not hit his child in the face in any way. He did not do that; he is emphatic about that. He put his hands on him, yes, because the confrontation was spiraling out of control.”

Any accusations beyond that, according to the source, are “a combination of exaggerations and lies. They have taken the overall smallest kernel of truth – that a fight got out of hand and reached a regrettable peak, and that as a result DCFS is looking into it – and they are manipulating it to best suit their attempts to gain custody.”
