An altercation between two passengers on a
Flight 2010 left
One person aboard tweeted that the dispute was over a passenger reclining a seat.
Comedian Mark Curry, who hosts a radio show in San Francisco, told NBC Bay Area that he awoke to the victim's shouts.
"The woman was saying he grabbed her neck. 'He choked me, he choked me! He hit me in the head!'" Curry told the station.
Southwest described the incident as a "physical altercation by one passenger against another," and said the pilot opted to declare an emergency on the flight to give it priority to land over other in-bound flights.
The jet returned to a gate where law enforcement was waiting. One passenger was removed from the flight, and the remaining 136 passengers continued their journey to San Francisco just after midnight. The FBI is handling the investigation and did not arrest the passenger, officials said.
