Inside ‘Zombieland’ airport infested with bedbugs where ‘hidden city’ of the homeless sleep on every level of terminal

TOURISTS arriving at the largest airport in Spain are welcomed with harrowing sights of sleeping 'zombies'.

Adolfo Suárez Madrid-Barajas Airport has turned into an apocalyptic city infested with bedbugs and homeless taking shelter on every level of the terminal.

Almost 500 "unauthorised occupants" live on the airport premises to avoid rough sleeping on the cold streets.

El Mundo's report said: "What began as a large group of homeless people spending the night, night after night, on Level 1 of Terminal 4 of Adolfo Suárez Madrid-Barajas Airport has finally become overwhelming.

"They can now be found on any floor, in any corner, despite the temperature reduction at nightfall or the constant messages over the PA system that resonate every few minutes."

Tourism bosses fear that a recent increase in reported drug use and violence among the population may deter tourists from visiting the capital city.

Terminal 4 has turned into the epicentre of the crisis with dozens men and women seen laying down on the floor.

The homeless occupy any available spot from restaurant tables to lavatory entrances.

A puddle of urine on the floor is a common sight with the drunk people relieving themselves where they sleep.

According to the Spanish newspaper El Debate, employees are planning to complain to the Ministry of Labour about the "more than obvious risk" to their well-being.

Airport workers have reported having insect bites, leading to the airport's managing body to hire pest control.

The company has had to fumigate hallways, furniture, and even check-in belts for bedbugs, ticks, and cockroaches.

But a Naturalia report into the alleged outbreak isn't such a big deal, suggesting that the bites were "a one-off incident with no determined origin".

Spanish reports also state that crack and other drug use, as well as prostitution, are widespread amongst the population.

Some residents have also been caught in possession of knives, machetes, and other handmade weapons.

Many are residing in the airport as they struggle to live in a city where living and housing costs have rocketed in recent years.

Fernando from Peru has been living at the airport for several months and told DailyMail: "You definitely have to sleep with one eye open.

"There are some bad eggs here who will rob you while you sleep, they usually come out at 3am, they'll take your phone, cigarettes, or whatever they can grab.

"A lot of the people are working for cash during the day in the black economy, then come back with alcohol and get drunk on whiskey and rum. Many have been living here for years."

Police often patrols the terminal, checking the residents' documents and looking out for any criminals wanted by the authorities.

Tensions amongst the occupants are also common with brawls breaking out every now and then.

The UGT trade union has slammed the government over the tackling of the issue.

They said in a statement: "Workers are exposed to dangerous situations in an environment that has not been designed or prepared for this type of problem.

"Travelers themselves, unaware of this situation, are also suffering the consequences, facing an environment of insecurity unbecoming of a key infrastructure for the country."

Meanwhile, NGO workers who support the homeless have also accused the government of failing the vulnerable group.

Gaspar Garcia, head of the Despega project at the Bokatas NGO added: "Instead of seeking housing or inclusion solutions, they have decided to relocate them to a very specific area - on the first floor of Terminal 4 - without basic conditions: no cleanliness, no security, no opportunity for real rest."
