The FBI said it is “continuing to gather facts” about allegations against Brad Pitt regarding his children while aboard a private jet.

“In response to your inquiry regarding allegations within the special aircraft jurisdiction of the United States; specifically, an aircraft carrying Mr. Brad Pitt and his children, 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 Thursday evening to Variety.

According to the LA Times, the FBI was informed of “a child welfare incident.” According to the report, citing a law enforcement official, the incident involved unruly behavior by Pitt while his children were present. The source also told the LA Times that the Los Angeles County Department of Children & Family Services is conducting an investigation into Pitt’s behavior. The DCFS told Variety earlier on Thursday that it was not able to comment on the reports.

Earlier on Thursday, the Los Angeles Police Department denied that it was conducting an investigation into Pitt. The alleged incident took place on Sept. 14 on a private jet flying from France to Los Angeles, with a stop in Minnesota.

A source close to the situation told Variety that the FBI received a complaint from state officials. While the FBI might not usually look into such a case, the source said that because the alleged incident happened while in the air, it moves to the FBI to gather evidence to determine whether or not a federal investigation is necessary.

News broke on Tuesday that Angelina Jolie filed from divorce from Pitt. According to court documents, Jolie is requesting full custody of their six children. The grounds for divorce are listed as “irreconcilable differences.”

“I am very saddened by this, but what matters most now is the wellbeing of our kids. I kindly ask the press to give them the space they deserve during this challenging time,” Pitt said in a statement to People on Tuesday.
