According to a statement released by the bureau, "the FBI has conducted a review of the circumstances and will not pursue further investigation."
There were no charges filed, the statement said.
A rep for Pitt did not immediately respond to ABC News' request for comment.
Two months ago, a source told ABC News that Pitt, 52, had been accused of child abuse after he argued with one of his children while aboard a flight from France to the United States. The Los Angeles Department of Children and Family Services also launched an investigation into the alleged incident, and earlier this month, cleared Pitt of wrongdoing.
The news of the alleged plane incident broke shortly after the "Allied" actor split from his wife of two years, Angelina Jolie-Pitt. The stars had been a couple for a decade or so, and share six children: Maddox, Pax, Zahara, Shiloh and twins Vivienne and Knox.
