When a Southwest Airlines flight attendant asked a passenger in the last row to prepare for landing on Sunday, the woman leaped to her feet, video shows.

Then Vyvianna Quinonez, 28, punched the flight attendant’s face, video captured by another passenger and obtained by the Sacramento Bee shows. Eventually, another passenger jumped in to stop the attack.

“Sit down!” yelled the man, who stood between Quinonez and the flight attendant, whose face was bleeding. “Don’t you dare touch a flight attendant like that.”

The assault caused the flight attendant to lose two teeth and suffer injuries to her face, The Washington Post’s Hannah Sampson reported earlier this week.

Quinonez, who was escorted out of the plane by police once it landed at San Diego International Airport, was arrested for battery, the Port of San Diego Harbor Police said in a statement.
