CCTV Footage Shows Hero Disarm Monterey Park Gunman Who Wanted To Shoot Up Second Dance Hall

A video of a man disarming the suspected Monterey Park shooter shows him wrestling the gun away and potentially preventing more carnage at a second dance hall minutes after the gunman killed 11 people and wounded at least nine more at the first site.

Brandon Tsay, 26, has been hailed as a hero for disarming the Monterey Park shooter at a dance hall in Alhambra, California.

Harrowing video obtained exclusively by NBC News captured the men tussling in what appears to be an empty lobby in the dance hall.

An armed man, dressed in dark clothing and a hat, walks out of the picture and about 30 seconds later is seen struggling with Tsay as the two wrestle over the weapon. A shoving match ensues, and Tsay manages to take the gun away from the man.

The weapon has been described as a "semi-automatic assault pistol."

The man then punches Tsay in his head while Tsay holds the weapon. The men continue to struggle before Tsay pushes the man off. The man continues to reach for the gun before he gives up and walks out of the room.

Tsay then points at the man and briefly moves out of the camera's view before he returns, with the gun in his right hand and using a cellphone with the other.

The entire ordeal lasted about 4 minutes.
