A passenger on Delta Flight #1404 from Los Angeles to Salt Lake City told us a first class passenger, described as "swarthy," was yanked off the plane at landing by security after "erratic behavior" during the flight. UPDATE BELOW.
Two Chevy Tahoe police cars drove up to the flight after it taxied to a stop, officers entered the plane and led the passenger away in handcuffs.
UPDATE: From Salt Lake City airport:
"There was no arrest, and no handcuffs, there were some complaints from co-passengers about this gentleman's behavior on the aircraft, police officers met him and let him know he had to have more of a public attitude on the airplane and he was allowed to reboard and travel to Chicago."
