The everyday guy-turned-hero who disarmed the Monterey Park mass shooter wasn't afraid to step in and get physical, and new surveillance video shows just how brave he was in the pivotal moment.
The video was taken Saturday evening, moments after 72-year-old Huu Can Tran entered a popular dance studio in Alhambra, CA.
From the video ... you'll see 26-year-old Brandon Tsay, who helps run the ballroom, confront the suspect, who is holding an assault pistol with an extended magazine. It apparently had a large silencer as well.
At the time, Tsay did not know, but later realized the same man had opened fire at another dance studio nearby in Monterey Park 20 minutes earlier ... killing 11 people and injuring 10 others.
The 2 guys seemed to exchange a few words, before Brandon charges at the suspect in the lobby ... and a fight breaks out between them over the firearm. Brandon eventually takes control of the weapon, and Tran runs out the door.
As we told you ... Brandon later spoke about the moment, saying something just came over him when he saw the firearm and sprung into action. Apparently, he didn't even know about the shooting that happened minutes before he confronted Tran.
As you know, Tran also wounded 10 others during a separate festival at Star Ballroom Dance Studio in Monterey Park -- not far from Tsay's ballroom. Law enforcement surrounded his van Sunday in Torrance, where police later confirmed he died by suicide.
As for Brandon, he sat down with Gavin Newsom Monday ... and he seems to be getting his flowers for the courageous act that likely preventing a second mass shooting
You know what they say -- not all heroes wear capes.
