An armed citizen shot and killed a gunman after he allegedly opened fire in an Oklahoma City restaurant Thursday night.

CNN reports that a man entered Louie’s Grill & Bar in Oklahoma City and began shooting. He then walked out of the restaurant and was shot dead by an armed citizen.

Two people — “an adult female and a juvenile female” — were shot when the attacker opened fire in the restaurant, and a man broke his leg trying to flee the scene.

The Oklahoma City Police tweeted:
