A United Airlines passenger was taken into custody Thursday after opening an emergency exit during his flight and sliding down the wing while the plane was moving, authorities said.

The incident occurred after the flight from San Diego landed at Chicago's O'Hare International Airport after 4:30 a.m., according to the report.

The man opened the door while the plane was taxiing to its gate, the report noted.

"I think everybody on the plane was just surprised and kind of shocked as he was going out," one witness said. "I heard everybody yelling, 'No, no, no,' and he just went out the exit door and onto the wing. ... Even the stewardesses came back and said, 'What just happened?'"

Another witness explained that the man did not even use the emergency exit by his seat.

"He crawled over one person and then three people on the other side and went out that door," according to the witness.

The passenger was soon restrained and arrested by police, according to the report.
