The FBI says it is gathering information about an alleged incident involving Brad Pitt and his children aboard a private flight last week.
Pitt, Jolie and their family flew into a Minnesota airport on September 14 - and gossip website TMZ, citing unnamed sources, reported that the stop came after Pitt became verbally and physically abusive to his children while on the private flight from France to the U.S.
On Sept 22, the Los Angeles Police Department denied that it was conducting an investigation into Pitt.
"We are not handling an investigation, and we do not have any details about the incident", LAPD Officer Tony Im told Patch.
It is claimed he continued ranting on the tarmac after the plane had landed - and that he even attempted to leave in a fuel truck.
Jolie lists the date of separation in her divorce filing as 15 September.
The allegations of abuse came from an anonymous call to the Los Angeles Department of Child and Family Services.
The LAPD, meanwhile, denied it was investigating the actor.
Vanity Fair has also contacted Pitt and Jolie's representatives for comment and will update this story as more news becomes available.
However, the source said Pitt was adamant "it did not reach the level of physical abuse, that no one was physically harmed". We are not investigating any case, nor do we have any allegations against Mr. Pitt.
The FBI has confirmed it is "evaluating" an alleged incident involving the actor Brad Pitt on a private jet transporting Pitt, his estranged wife Angelina Jolie and their children.
A source told Mirror Celebs the FBI is investigating the claims as a jurisdictional issue due to the alleged incident taking place in the air. Robert Offer, an attorney for the family, said Jolie's decision was made "for the health of the family", according to an Associated Press report.
The Los Angeles Police Department is not investigating any reports or allegations of child abuse against Pitt, a spokesperson previously told PEOPLE.
