The Underworld Podcast

Melbourne has been gripped by a new wave of underworld gang wars, this time fueled by the booming billion dollar black-market tobacco trade. Firebombings, drive-by shootings, and extortion targeting shops across the city have roiled the city as middle eastern syndicates and biker gangs fight over profit. At the center of the chaos is underworld figure Kaz Hamad, whose name keeps surfacing as rival crime crews battle for control of a trade worth tens of millions.

When a 2023 club brawl ended in a Freetown, Sierra Leone parking lot shooting, cops and reporters pointed the finger at “Omar Shariff,” a portly Turkish millionaire who’d spent much of the past six months throwing cash about at the city’s casinos and top-end restaurants.

We told you his life story in our 2022 episode, and now we're back with the sequel.

After years on the run with a huge U.S. bounty on his head, Mexican forces killed him in a daring military operation last week in Jalisco.

The cartel responded with unprecedented retaliation: burning vehicles, massive roadblocks and bloody clashes with security forces that left dozens dead and airports and flights disrupted. His death has left a power vacuum in CJNG, sparking fear of a new wave of turf wars and uncertainty about what comes next in Mexico’s cartel wars.

Monk Eastman ruled the depraved streets of turn-of-the-century Manhattan with fists and absolutely zero regard for human life, commanding an army of 1,200 thugs who terrorized the Lower East Side. At the height of his power, he was pulling cash from every racket you could think of while rigging elections for Tammany Hall and overseeing street violence so extreme that cops needed reinforcements just to enter his territory.

Eastman represented a true transition in the evolution of the underworld, when crime became organized. All that, and he managed to become a war hero too, before the street life finally caught up with him.
