CHICAGO (CBS) — An apparently drunken Southwest Airlines passenger ran screaming onto a Chicago-bound flight in Las Vegas, after having been kicked off the plane, and he was zip-tied to a seat until police arrived.

Cell phone video of the incident on Flight 3630 shows an airline employee pinning the man to the floor of the plane at McCarran International Airport around 7:30 p.m. Pacific time Monday.

Passengers said the man earlier had been holed up in the restroom while the plane was at the gate until employees kicked him off the flight. After he was kicked off, the man ran back onto the plane, and a crew member tackled him and pinned him down.

“He was already boarded, and he went into the bathroom, and they just told us they were trying to get him out of the bathroom, and they took him off the plane,” Rick Alonzo said. “Next thing you know, he tried to fight his way back on, and that’s when the Southwest guys came and got him.”

Southwest Airlines said the passenger was being unruly, and appeared to be intoxicated.

Video shows a Southwest employee holding the man on the ground while waiting for police. The man was eventually zip-tied to a seat before three Las Vegas police officers arrived and removed him from the plane.

“He was violently getting back on the plane, like pushing people, so one of the guards tackled him in front of my feet,” Molly O’Malley said. “He was acting very inappropriate.”

Alonzo said the man was still yelling when he was removed from the plane the second time.

Passengers said one flight attendant was injured in the scuffle, and did not fly to Chicago.

“The crew did handle it in a respective way, but it was very scary, and as someone who does fly often, I felt unsafe at first, but at the end of it, they figured it out,” Alyssa Bergamini said.

The flight arrived at Midway International Airport around 2 a.m., about an hour late.

Southwest Airlines issued the following statement about the incident:
