A teen in St. Louis allegedly stole a tip jar from a restaurant and assaulted a customer, leading one of the eatery's owners to try and save the day by opening fire.
Now, the shooter faces criminal charges, police say.
According to authorities, the 16-year-old and another teen caused a disturbance inside a Utah Station restaurant.
The teens left the restaurant, but the 16-year-old stole a tip jar on his way out the door, police said.
News 4 reported a witness said a group of customers followed the teens out of the restaurant.
This is when the teens stopped, turned around and started walking towards the customers, police said.
Authorities said the 16-year-old shoved a 56-year-old customer to the ground and started beating on him. The restaurant co-owner left the business and then shot the 16-year-old, officials said.
The assaulted customer is a frequent visitor to the restaurant and a friend of the co-owner, who was just “protecting his friend,' a witness told News 4.
Authorities said they arrested Sam Bauer, 52, on suspicion of first-degree assault, but the case is still under investigation and the evidence has not been given to prosecutors.
Prosecutors will decide if the shooting was justified, police said.
The 16-year-old was taken to a local hospital and listed in stable condition, officials said.
