BATON ROUGE, La. (AP) — Authorities say a security guard at a Louisiana hookah lounge shot and killed a man and wounded two others following a fight at the business.

Baton Rouge police spokesman Sgt. L’Jean McKneeley tells news outlets 40-year-old Derrick Johnson pulled out a handgun and tried to go back inside after security officers escorted the group out Saturday. When the officers attempted to stop Johnson, police say he threatened them with a gun, at which point one opened fire.

Johnson died at the scene. Two unidentified people were hospitalized with gunshot wounds. McKneeley said their injuries aren’t considered life threatening.

An investigation is ongoing, and McKneeley says it’s too early to tell if the guard will face charges. Police haven’t identified any of the guards or the company for which they work.
