New charges were filed Thursday in the case accusing Tekashi 6ix9ine of being a violent gang member, but the rainbow-haired rapper is not named as a defendant in the updated indictment, a possible indication that he could be cooperating with the feds.

Manhattan prosecutors brought federal racketeering and firearms charges against the 22-year-old hip hop artist in November which alleged he’s a member of the violent street crew “Nine Trey Gangsta Bloods.”

Three new defendants were added to the now-10 person-indictment but Tekashi — given name Daniel Hernandez — who was on the initial indictment was missing from the new court papers. Neither the US attorney’s office nor his lawyer, Dawn Florio, would confirm if Hernandez had flipped on the gang and is working with the feds.

A sealed document was filed in his case yesterday.

Anthony Ellison, Denard Butler and Kintea McKenzie were newly charged in the superceding indictment.

The court papers reveal that McKenzie, aka “Kooda B,” and Tekashi’s former manager Kifano Jordan, aka “Shottie,”have been charged for allegedly shooting at Tekashi’s rival, rapper Chief Keef, in Midtown in June.

“It could be that he may have pled guilty to a cooperation agreement,” Paul Krieger, a former prosecutor in the Manhattan US attorney’s office, said of the fact that Tekashi’s name wasn’t on the new indictment.

“It’s not unusual to do a cooperation agreement under seal to protect ongoing investigations, to protect witnesses or cooperating defendants,” said Krieger, who is now a white-collar criminal defense lawyer.

“In my experience if you haven’t pled [guilty] publicly and you’re taken off the indictment, you’re cooperating,” a federal criminal defense lawyer said.
