An Idaho man accused of uttering a racial slur and slapping a crying 19-month-old boy on a Delta Air Lines flight has surrendered to federal authorities.

Joe Rickey Hundley of Hayden, Idaho, turned himself in to federal officials in Idaho on Tuesday morning, the U.S. attorney's office in Atlanta said.

Hundley was recently charged with assaulting a minor in the February 8 incident. According to court documents, Hundley, during a flight to Atlanta, allegedly told the baby's mother to "shut that (N-word) baby up."

He then turned around and slapped the child in the face with an open hand, according to the documents.
