The 57-year-old Russian woman, who stowed away on a Delta Air Lines flight from New York to Paris last week, is scheduled to return to the United States on Tuesday, a French airport official confirmed to CNN.

The woman, who passed through several security checkpoints at New York’s John F. Kennedy International Airport and boarded a plane to Paris, will depart France on a flight at 2:30 p.m. local time (8:30 a.m. ET), the official said.

She was scheduled to fly to the United States on Saturday afternoon, but French authorities removed her from the plane after she began screaming, the official said.

A man who was on the plane told CNN that the woman was sitting across from him and his family in the aisle.

“She kept saying, ‘I don’t want to go back to the United States.’ “Only a judge can force me to return to the United States,” said Gary Treichler.

The woman will be accompanied by six US marshals on the flight back to New York on Tuesday, authorities said.

Authorities in the US are continuing to investigate how the woman sneaked onto the first Delta flight without a ticket.

Transportation Security Administration inspectors are preparing a civil case against the stowaway after reviewing airport security videos from John F. Kennedy International Airport, agency spokeswoman Alexa Lopez told CNN.

“TSA will pursue civil proceedings against passengers if there is evidence that procedures may have been violated,” Lopez said. The TSA cannot file criminal charges, but it can refer them to the Department of Justice.

Delta has not said how the woman was able to board the plane after passing through the TSA checkpoint.

The airline said it was “conducting a full investigation into what may have happened” but declined to comment further.
