Tekashi 6ix9ine

Tekashi 6ix9ine will cool his heels in jail following his arrest on federal RICO and firearm charges. A judge on Monday denied his offer of $1.1 million — his entire bank balance as collateral for bail.

Tekashi, whose real name is Daniel Hernandez, was taken into custody along with his ex-manager, Kifano “Shottie” Jordan, and two other men late Sunday night.

The arrests came after the rapper fired his entire management team and booking agency for reportedly stealing over $3 million from him.

Federal agents heard his ex manager and others threatening his life on phone taps. Te phone taps picked up the manager saying he wanted to “super violate” Tekashi.

The feds picked up Tekashi last week, took him to Homeland Security’s New York City headquarters and offered him protection, according to the Dailybeast.com. But the 22-year-old rapper refused.

He was driven home and kept under 24-hour surveillance until his arrest on Sunday.

The 17-count indictment, which was unsealed late Monday, charged Tekashi, Jordan, Raheem “Crippy” Walter, and Fuguan “Fu Banga” Lovick with being members of a violent street gang, Nine Trey Gangsta Bloods.

The indictment charged Tekashi and the three men with firing shots at a rival gang member who disrespected the Trey Nine gang. The shooters missed their intended target and hit an innocent bystander in Brooklyn.

The indictment also accused the men of “brazen acts of violence” and peddling fentanyl and other narcotics on the streets for financial profit.

The troubled rapper appeared visibly shaken when he was escorted into the courtroom in chains on Monday afternoon.

With his rainbow hair pulled away from his face, Tekashi sat with his eyes closed as he listened to the charges against him.

He answered the judge’s questions in a soft, polite voice, according to the Dailybeast.com.

His mother, who pleaded for his freedom in an earlier criminal case months ago, fought back tears as she sat between federal agents who closely guarded her in court.

Tekashi’s attorney offered all the cash in the rapper’s bank accounts — $1.1 million — as collateral if the judge granted bail. But the judge ordered him held until his next court date.

TMZ has learned the rainbow-haired rapper is not receiving special treatment while in jail. He was placed in general population with the other gang bangers.

Tekashi was already on probation for using a 13-year-old minor in a sexual performance and for assaulting a police officer.

Tekashi plead guilty in both cases and received probation of up to 5 years. The judge in the case involving the minor child warned the rapper to stay out of trouble or his probation would be revoked.

He faces a minimum of 32 years in prison if convicted on the federal charges.
