teams using a product specially developed for SBASE that allowed the removal of graffiti without damaging the livery of the cars. Cleaning the 410 vandalised cars had cost the City of Buenos Aires AR$ 10.25 million, while a coat of anti-graffiti paint has been applied to the cars to make future cleaning easier using alcohol. SBASE, along with the Buenos Aires Metropolitan Police, has adopted a zero tolerance policy on graffiti in the Buenos Aires Underground, imposing fines ranging from AR$400–6000 and up to 30 days community service, the culprits often being made to clean the cars they vandalised. Increased vigilance from over 500 police officers, as well as close to 300 CCTV cameras, have aided in decreasing new acts of vandalism by 85% in 2014, with a further decrease of 50% in 2015 after security was intensified. Painted cars were often worked on by organised groups in a "whole car" (graffiti jargon for covering the entire visible surface of the vehicle) manner, severely reducing visibility from inside the cars. Numerous arrests have been made on these groups which often consist of foreign nationals from countries such as Chile, Germany and France; two German nationals and a Chilean national were arrested in January 2016. One high-profile arrest of such a group saw four Argentines detained in 2015 after vandalising a 200 Series train on Line A. Their houses were subsequently raided, uncovering a vast collection of stolen Subte paraphernalia as well as documented evidence of their activities in the form of videos and photographs. According to Clarín, people from across the world have visited Buenos Aires with the sole purpose of "bombing" (painting cars in a clandestine manner), while competition among different groups exists in the form of greater points being earned for painting newer cars or the level of danger experienced. In most cases, the people involved are university educated and with stable employment. In January 2016, a group called Soketes Calcetines was discovered to be offering tourists graffiti tours of the Underground, giving them a chance to paint cars for a fee. The group documented their activities and uploaded them to YouTube in order to promote the business, which has been subsequently shut down with its members arrested. In popular culture The Buenos Aires Underground is featured in the 1996 science-fiction film Moebius, directed by Gustavo Mosquera. In the film, the circumstances surrounding the disappearance of an underground
