Ross Kemp on Gangs is a documentary series that was broadcast on Sky 1 from 21 September 2004, until 6 January 2009.

[1] Hosted by actor Ross Kemp, the series follows Kemp and a film crew around the world as they interview members of gangs, locals who have been affected by gang violence, and the authorities who are attempting to combat the problem.

In the third series, Kemp travelled to Kingston, Jamaica, where gangs engage in bloody turf war; Poland, where football hooligans have become some of the most feared gangs in Europe; Colombia, where Kemp meets the people involved in bitter guerrilla fighting – including the most secretive of them all, the Sicarios; and travels to East Timor to meet the Sacred Heart and Seven Seven, two gangs in the midst of a deadly conflict.

In the fourth series, Kemp travelled to the Los Angeles district of Compton, to a neighbourhood where a famously hazardous scene was filmed, in which gangland junior Matt 'Malicious' Ward misfired his gun in a rival gang's neighbourhood.

[4] In early 2009, the series aired in the United States on the Investigation Discovery channel under the title Gang Nation.
