A man who sued members of Patti Labelle's entourage over an alleged airport attack in 2011 has lost his bid for a new trial.

Richard King claimed he suffered traumatic brain injuries after an encounter with LaBelle's son and manager Zuri Edwards, bodyguard Efrem Holmes and hairdresser Norma Harris at the Bush Intercontinental Airport in Texas.

He alleged the injuries forced him to drop out of The United States Military Academy at West Point, but a federal judge cleared the defendants of any wrongdoing in September (14).

King appealed the ruling and demanded a new trial, insisting Harris' own testimony, in which she admitted to pushing him, should have been enough to find her guilty of assault.

But U.S. District Judge Keith Ellison, who presided over the trial, dismissed the motion on 14 November (14).

The Lady Marmalade hitmaker was initially named as a defendant in the original lawsuit, but her name was later dropped from the legal action.
