The U.S. Military Academy says a cadet who is suing R&B diva Patti LaBelle over a scrape at a Houston airport has left the academy at West Point.

A West Point spokeswoman says Richard King left the academy Monday. Lt. Col. Sherri Reed cited privacy laws that prevent her from saying if his exit was related to the lawsuit or the altercation.

The academy acknowledges it investigated the March 11 incident. King says he was in his hometown airport standing near LaBelle's luggage when three of her bodyguards attacked him. In court papers, he says LaBelle thought he was standing too close to her bags.

Video shows King on the phone and a shoving match ensuing, with three people pushing and punching King. His lawyer says he suffered a concussion.
