Ferrocarril Clandestino (2010). Informe de investigación sobre controles, identificaciones y detenciones. Madrid. 

This report has been prepared based on testimonies collected from June 2009 to March 2010 on massive identity checks and selective individual identifications. The document is divided into two parts: in the first part, the concrete results of the study are developed, and in the second one, some of the anonymous testimonies offered by different people who have gone through these controls are displayed. Most of the identifications reported in the testimonies occurred in areas of Madrid where the presence of migrants is greater: neighborhoods such as Lavapiés, Embajadores, Atocha, Vallecas, Estrecho, Tetuán, Cuatro Caminos, Orcasitas or Plaza de Castilla . These are daily scenarios for this type of action, while other areas of the city where there is not the same presence of migrants are free of such controls.
