TMZ Sports has obtained video moments after UFC star Brian Ortega allegedly slapped a Korean man at UFC 248 ... and you can hear Ortega say, "I told you I'd slap you like a bitch."
It all went down in the stands at T-Mobile Arena in Vegas on Saturday -- when 29-year-old Ortega approached Jay Park, a Korean musician who recently served as a translator for Korean UFC fighter Jung Chan Sung (known as "Korean Zombie").
Ortega was reportedly upset with Park over comments he made while translating for Korean Zombie during a recent appearance on "Ariel Helwani's MMA Show." Park had claimed Ortega "ducked" a fight with Zombie, which Ortega has adamantly denied.
Things came to a head on Saturday. At 4 seconds into our video, you can hear a slap sound -- followed by commotion and Brian bragging that he slapped Park.
Ortega was escorted out of the arena. Security checked in with Park, who appears to be okay.
After the incident, Park told media he filed a police report with local officials. Unclear if Ortega will be charged with a crime.
We've reached out to Ortega's camp for comment. So far, no word back.
