The child abuse allegations against Brad Pitt have been referred over to the FBI ... TMZ has learned.
As we reported, the L.A. County Dept. of Children and Family Services received an anonymous call that Brad was wasted on a private jet last week and became physically and verbally abusive to his kids.
As we reported, the DCFS followed protocol and notified the LAPD. Law enforcement sources say the LAPD's Abused Child Unit (ACU) got the report, but determined that the Department did not have jurisdiction because the alleged incident occurred in the air, on a flight from France to the U.S.
We know ... the plane landed a week ago Wednesday just before 8 PM at an airport in Minnesota. That's when eyewitnesses say Brad was "out of control" on the tarmac and even tried to leave in a fuel truck.
Our LAPD sources say because the incident occurred in the air, the FBI has jurisdiction. The ACU then closed its file and referred the matter to the FBI.
As we reported, DCFS has already interviewed Brad and Angelina separately and they will also interview the kids. Our LAPD sources say if those interviews produce information suggesting there was possible abuse at their L.A. family home, the LAPD will open a new case.
Our Pitt sources say the actor denies committing any sort of abuse.
