A woman who managed to get on a Delta Air Lines flight in New York as a stowaway was arrested when the flight landed in Paris this week.

The woman, who has not been publicly identified, got onto Delta Flight 264 from John F. Kennedy International Airport on Tuesday, arrived at Paris Charles de Gaulle Airport and was soon discovered.

The stowaway was taken into custody by French border police. The woman is 55 to 60 years old, has a Russian passport and will be sent back to the U.S., French airport officials said, according to CNN.

A Transportation Security Administration spokesperson told CBS News that “an individual without a boarding pass was physically screened without any prohibited items. The individual bypassed two identity verification and boarding status stations and boarded the aircraft.”

In addition to getting past security, the woman entered the plane by going past Delta personnel at the gate.

“Nothing is of greater importance than matters of safety and security. That’s why Delta is conducting an exhaustive investigation of what may have occurred and will work collaboratively with other aviation stakeholders and law enforcement to that end,” Delta Air Lines said in a statement.

A passenger on board said the woman repeatedly used the bathrooms during the flight.

“Apparently, she hid in a lavatory all the way at the rear of the aircraft when we departed JFK. … I overheard the flight attendants talking about it with the pilots — they said this person was in one lavatory and then would exit and walk to a different lavatory and go in there for a long time,” Rob Jackson told CNN.

Once the stowaway arrives stateside, she will face charges from the Port Authority of New York and New Jersey that include theft of service, unspecified law enforcement sources told the New York Post.
