Dallas PD officer arrested in Lancaster for displaying AR-15 style rifle during argument

A Dallas Police Department officer has been arrested for reportedly displaying an AR-15 style rifle during a "heated" argument early Saturday morning.

John Rozell, 34, was arrested by Lancaster PD on a charge of disorderly conduct by displaying a firearm in public.

Lancaster police said this incident started just before 2:30 a.m., in the 1400 block of I-35.

Responding officers were told a man, later identified as Rozell, was involved in a "heated argument" with another man in a parking lot.

During the argument, Rozell reportedly went and got an AR-15 style rifle, before displaying it while approaching the other man.

That’s when someone called 911.
