The parents of a girl who reported being inappropriately touched by a man while flying alone from New York to Iowa have sued the man and American Airlines, saying the airline failed to protect the girl.

Muhammad Asif Chaudhry was arrested after the July flight on charges including engaging in sexual contact with a victim between the ages of 12 and 16. The Pakistani citizen has denied the accusations. He's been released on bond.

The lawsuit alleges he moved to an open seat beside the girl, who reported being woken up by the inappropriate touching. She alerted a flight attendant when Chaudhry left to use the restroom. The FBI met Chaudhry when the flight landed.

American Airlines says it's cooperating with law enforcement and cares deeply about its young passengers.
