The 23-year-old and his Nine Trey gang came face to face with his rival Casanova at a boxing match at the Barclays Centre in New York last November. While the video has no sound, it is clear when a shot is fired, as the masses fall to the floor and begin to scramble for safety.
Nobody was hit by the bullet, but Tekashi 6ix9ine - real name Daniel Hernandez - was subsequently arrested and in February he pleaded guilty to racketeering conspiracy and eight other charges.
In a statement on behalf of the United States Department of Justice, Attorney Geoffrey S. Berman, explained how Hernandez and his gang had spread violence across New York.
He said: "As alleged in the indictment, this gang, which included platinum-selling rap artist Tekashi 6ix9ine, wreaked havoc on New York City, engaging in brazen acts of violence.
"Showing reckless indifference to others' safety, members of the gang were allegedly involved in robberies and shootings, including a shooting inside the crowded Barclays Center, and a shooting in which an innocent bystander was hit."
Hernandez could face a mandatory minimum 47 years in prison, however, he has made a plea deal in a bid to avoid prison time. In doing so, he has testified against former alleged gang-members Anthony 'Harv' Ellison and Aljermiah 'Nuke' Mack, who are accused of racketeering, and claimed that rappers Cardi B and Jim Jones were members of the notorious Bloods gang - something which Cardi B has since denied.
If his plea deal is a success and the rapper does avoid jail, it is unclear where he will go instead. It's been reported that Hernandaz may be offered witness protection, which isn't really surprising given that he has already been dubbed 'Tekashi Snitch 9ine' by many in the rap game.
However, his rather unsubtle tattoos might be a bit of an issue there. According to the New York Times, if feds do offer him witness protection, it's unlikely they'll go to the expense of having his facial ink removed. Given that one of them is a massive '69' that might be a problem.
The report reads that 'it is unlikely the United States Marshals Service, which runs the witness protection program, would pay for the removal of Mr. Hernandez's signature face tattoos'.
But one expert reckons it might not be so hard for Hernandez to blend into a new environment.
Jay Kramer, a former FBI official who has worked on organised crime cases, told the New York Times: "Despite how connected we are, and the appetite for social media content in this country, there are places where, if this kid gets a haircut and wears normal clothes, no one would know or care who he is."
Hernandez is due to be sentenced in January.
