According to AP, he has publicly identified himself as a member of a violent gang, 9 Trey Bloods.
Tekashi was indicted on six counts: conspiracy with others to commit racketeering, discharging a firearm while committing a crime, committing a crime of violence in aid of racketeering, assault with a unsafe weapon, carrying a firearm, and committing a crime in aid of racketeering.
The Brooklyn-based rapper, whose legal name is Daniel Hernandez, was arraigned before US Magistrate Judge Henry B. Pitman alongside five other men affiliated in the New York City-based gang, Nine Trey.
The authorities also arrested three of Hernandez's former associates, Kifano "Shotti" Jordan, Jensel "Ish" Butler and Faheem "Crippy" Walter.
Law enforcement sources told the outlet that 6ix9ine was cuffed by ATF agents in NYC at the same time his ex-manager Shottie was also arrested. Those acts could include murder, robbery, extortion and drug distribution, the court papers said. Tekashi's ex-manager is facing the same 6 charges. However, an innocent bystander was shot on a Brooklyn street corner as a result of the agreement, the indictment said. A spokesperson for the USA attorney's office confirmed the arrest to Fox 5's Lisa Evers.
As TMZ previously reported in late October 2018, Tekashi69, who found fame in 2017 with his song "Gummo" (via NBC 7), received four years of probation after pleading guilty to one count of Use of a Child in a Sexual Performance in 2015.
In a 2015 case in NY, 6ix9ine was sentenced to probation for his involvement in the video that was posted on social media.
