An employee of the Dallas County Sheriff’s Office has been arrested for allegedly pointing a handgun at a person after getting into an argument, the Dallas Police Department told The Dallas Express.

Dallas police responded to a “Disturbance Armed Encounter” call at 3 a.m. in the 400 block of West Commerce Street.

The suspect, identified as Lora Johnson, 61, got into a heated verbal exchange about a dog barking with the victim, whose identity is currently unknown.

The victim told police that a family member was dog-sitting, and Johnson made a complaint about the dog barking.

An argument ensued between the victim and Johnson, who then allegedly proceeded to hit the victim in the face and, at some point in the melee, pointed a gun at them, according to police.

Johnson, who was off-duty at the time, has been arrested and charged with aggravated assault with a deadly weapon. She was transported to the Dallas County jail.

The Dallas Express reached out to the Dallas County Sheriff’s Office for comment but had not received a response at the time of writing.

Dallas police will be heading the investigation, which is ongoing.
