8:31 AM PT -- 7/22 The man yelling the n-word has been ID'd as Joe O'Brien, also known by his adult film stage name, Dustin Gold. Gay porn company, Helix Studios, says he was one of their models 6 years ago ... but will not be working for them again in wake of the video.
11:35 AM PT -- Police are aware of the video and looking into it. According to the NYPD ... a politician notified them of the incident and they're trying to locate the precinct where it occurred. We're told a victim has not come forward to file a report.
A despicable man spewed a racist epithet at someone he felt was blocking his car ... then turned his vitriol toward the guy recording his disgusting behavior.
Check out this video from Brooklyn ... the racist gets out of his car and screams at a person to get out of the middle of the street, then unloads with the n-word.
He then realizes a guy walking by is recording the incident, and he seems surprised and pissed off, and then launches into a homophobic tirade followed by a full-on physical assault. The racist steals the man's phone and slams it on the ground.
The racist dude insists he doesn't care if the video gets posted online -- he even says he'll win fans because of it.
