A notorious Crips gang leader was arrested Monday – just as he was about to be sprung from prison – on fresh murder charges stemming from a 2015 hookah bar slaying in Brooklyn, authorities announced.

Larry Pagett, the head of the Eight Trey Crips, was indicted by feds in Brooklyn for allegedly gunning down Chrispine Philip inside the Buda Hookah Lounge in Prospect-Lefferts Gardens.

Prosecutors say surveillance video shows Pagett, 37, removing a gun in the crowded bar and shooting Philip several times in the back and head as he tried to flee.

Pagett, aka “Biz,” “Biz Loc” and “Molotovbizzz,” was due to be released Monday after served two years for violating his supervised release through his involvement in Philip’s slaying. He had never been formally charged in the killing.

He was arraigned in federal court in Williamsport, Pa. and will be transferred to Brooklyn to face charges.
