On the heels of LA County’s Department of Children and Family Services extending its probe into his parenting, In Touch has exclusively learned that Brad Pitt is also still under investigation by the FBI.

An insider reveals that the FBI began its investigation after the Los Angeles Police Department alerted them to a physical incident involving Brad on the plane. The FBI is currently investigating it as a possible assault case, which is a misdemeanor.

The case has taken a significant turn in Angelina Jolie’s favor, says another insider with knowledge of the investigation, adding that the fact of DCFS extending its investigation is not looking good for Brad. “DCFS could have closed this case and referred the family to a mental health professional,” says the insider. “The fact that they didn’t, the fact that they are still involved, shows it’s serious.”

Though Brad, who's rep de­nies he was abusive to his kids, remains cooperative with DCFS, he blames Angelina for prolong­ing the drama. “Brad’s disgusted with how Angie has handled the entire situation,” says the first insider. “It’s a very sad situation for everyone. He’s disgusted but she’s worried about the safety of their kids around him.”

“There is far more to this than has come out so far. One cru­cial thing is, this is never going to court,” the insider claims. “Brad won’t make it to court by the time this investi­gation closes. This is an independent investigation based on facts. And he is not going to be able to counter those facts in court.”
