Theroux goes inside Miami's 'mega-jail'

20 May 2011 Last updated at 09:53 BST

Documentary maker Louis Theroux was allowed inside Miami's main jail where a violent gladiatorial code rules amongst the inmates.

With about 7,000 inmates, the Miami jail is one of the biggest in America - a so-called "mega-jail".

Up to 24 inmates are crowded into a single cell, living behind metal bars on steel bunks, sharing a single shower and two toilets, and as Louis told BBC Breakfast, are often left to their own devices by overwhelmed prison officials.

The two-part documentary, Louis Theroux: Miami Mega-Jail, is broadcast on BBC Two on Sunday 22 and 29 May at 2100 BST.
