FLASHBACK: Brad and Angelina at the 2012 Golden Globes

Jolie, 41, filed for divorce from Pitt, 52, in a Los Angeles court, Monday and stated that she separated from the Allied star on Sept. 15 – just one day after the couple and son Maddox, 15, were involved in an alleged altercation aboard their private plane.

The actress requested sole custody of their six children: Maddox, Pax, 12, Zahara, 11, Shiloh, 10, and 8-year-old twins Knox and Vivienne.

Pitt is accused of being "verbally abusive" and getting "physical" with Maddox during a fight with Jolie that “escalated more than it should have,” a source with knowledge of the situation previously told PEOPLE.

The source said that Pitt did not hit Maddox, but “made contact” with him “in the shoulder area.” The source says there was no sign of physical injury on Maddox.

An investigation into the alleged incident has been launched by the L.A. County Department of Children and Family Services after it was reported anonymously. The case was also referred to the FBI under special aircraft jurisdiction since the incident occurred mid-flight, though the FBI is unlikely to launch a further investigation, a Pitt source told PEOPLE on Saturday.

The Pitt source said the actor is fully cooperating with the investigation and “takes the matter very seriously.”

It does not seem likely at this time that the FBI will be recommending further investigation into the matter, though, a source close to the actor told PEOPLE, Saturday.
