Shocking new images of Spain's 'airport cities' have emerged with homeless residents who have lived in terminals for up to seven years telling of the crime and violence they have endured.
At Adolfo Suarez Madrid-Barajas airport in the Spanish capital, a 'hidden city' of the homeless has been allowed to balloon over the past 10 years.
Brits have been warned over recent reports of alleged violence, drug use and insect infestations as the terminals have become overrun by the estimated 400 rough sleepers living at the airport.
Last week, pictures and footage taken by MailOnline showed dozens of men and women sprawled out on the floor of Terminal 4, the epicentre of the crisis.
In new images showing the airport crisis, the travel hub's dwellers are seen camping out on mattresses down corridors, with some seen perched up in spots next to toilet entrances and behind flight displays.
