OMAHA, Neb. (AP) — Omaha authorities say two men have been hospitalized for burns after a police officer fired his handgun and another fired his stun gun after breaking into a blazing apartment.

Officers and firefighters were dispatched around 7:35 a.m. Friday after someone reported a stabbing and that someone had poured gasoline on someone else. Police say the officers broke down an apartment door to get inside and that the shootings soon followed. Both men were sent to Creighton University Medical Center and then to a Lincoln burn center. Another person was treated for minor injuries.

Police officials say in a news release they’re uncertain whether the men were struck by either a bullet or the stun gun dart. No officers were injured. It’s unclear so far why the officers used their weapons.
