A customer with a concealed-carry license intervened to stop a gunman Wednesday inside a Dallas-area sports bar, FOX 4 reported.

The gunman and an employee were killed at Arlington's Caliente Sports Bar & Grill.

About a dozen customers were at the restaurant when a 48-year-old man walked in with a gun at around 6pm local time.

According to police, the gunman confronted a male employee and fatally shot him. At that point, a male customer who was at the restaurant with his wife engaged the shooter.

"He told his wife to get down and get away because he was carrying a firearm on his person. And he made the decision to engage the shooter at that point fearing there would be other loss of life or additional shooting at the restaurant," said Arlington Police Lt. Chris Cook.

Police said the man notified them that he has a concealed-carry permit for the handgun.
