NUDE passenger's bizarre behaviour has forced the diversion of a US Airways plane.

Keith Wright, 50, of New York allegedly disrobed in front of 148 passengers on flight 705 from Charlotte to Los Angles yesterday, an Albuquerque airport spokesperson said.

The flight crew become alarmed by his bizarre behaviour after he allegedly ran around the plane, refusing to put his clothes back on or be covered with a blanket.

Passengers helped physically restrain Mr Wright, who was eventually handcuffed to a row of seats, and the plane diverted to Albuquerque.

“We had to physically hold him down on the floor and handcuff his ankles, his wrist,” passenger Matt McGinnis told the US’s News 13.

Passengers were notified of a violent passenger, but everyone remained calm, a US Airways spokesperson said.

“I fell asleep and the lady fell asleep and I woke up and she was gone and I was like oh my God this guy is naked,” passenger Lynette Naude said.

Mr Wright was arrested, still naked, and was taken into custody.

The plane continued on to Los Angeles after his arrest, and passengers were treated to a different announcement, including “a reminder to everybody to please keep your clothing on”.

The FBI is investigating and is being charged with interfering with flight crew members and attendants.
