No-Go Zones - The World's Toughest Places

Tepito, Mexico (1x5)

:

Tepito in Mexico City - arguably the most dangerous black market in the world. At first glance, the no-go zone looks like any other market - yet the main thing you'll find lurking down the alleyways behind it is death. It's ruled by the La Union gang. The Tepito cartel deals in drugs, weapons and assassinations - anything that you can use money to buy.
