CHARLOTTE, N.C. -- Charlotte-Mecklenburg Police say one person has been fatally shot following an altercation inside Northlake Mall.

Just after 2 on Christmas Eve, reports began surfacing of a shooting inside of Northlake Mall. CMPD says preliminary information on the scene indicates there was an argument between two groups of people inside the mall. Officers, who were working off-duty at mall, responded, and an armed subject was shot by an officer during the altercation. In a press conference Thursday evening, CMPD Chief Kerr Putney said the armed subject pointed a gun at the officer before he was fatally shot.

The deceased, Daquan Westbrook, was pronounced on the scene by MEDIC.

Chief Putney says at this point, there's no indication this is gang-related, but it's certainly an avenue they're going to pursue during the investigation. Putney also said the subjects involved all have a history of gun violence.

No officers were injured during the incident.

Sarah Wise, a Bath and Body Works employee, was inside the mall at the time of the shooting.

"It was absolutely chaotic," she said, "All I heard was gunshots back to back, and literally everybody just flooded in the store saying, 'Shooter! Shooter! Shooter!' We just ran out the back and got out as fast as we could."

A video posted to YouTube shows people escaping the Northlake Mall Dick's Sporting Goods store in the aftermath of the shooting.

Authorities say those looking to reunite with loved ones at the mall are meeting at the AMC movie theater at Northlake Mall.

One viewer tells NBC Charlotte's Sonja Gantt that the shooting occurred near the Apple Store inside the mall. The mall was evacuated, but some users on Twitter shared stories of hiding inside stores until police had arrived.

MEDIC says they are treating one patient with a leg injury, one patient with an asthma attack and one patient in labor.

All ramps to and from Harris Boulevard to I-77 were closed down while police cleared the scene.
