Mexican drug lord “El Mayo” — who took over the notorious Sinaloa cartel from “El Chapo” — apologized for his reign of brutal violence Monday before being handed a life sentence in a New York federal courtroom.

Judge Brian Cogan also ordered the infamous 76-year-old gangster, whose full name is Ismael Zambada Garcia, to forfeit a whopping $15 billion.

“I am here to say I’m sorry for the harm I caused, and the example I set,” the elderly kingpin said before learning his fate in Brooklyn federal court. “I accept my punishment. I am not here for compassion.”

But the feds admitted in court that they have yet to recover any of the ruthless narco bosses’ ill-gotten gains.
