In early 2020, at least four officers of the National Police Corps infiltrated several social movements linked to Catalan independence. Using false identities, Maria Perelló infiltrated in Girona; Ramon Martínez, in Valencia; and Daniel Hernández and Marc Hernández, in Barcelona. All were part of the 33rd graduating class of the Ávila Police Academy and operated under the orders of the General Information Commissariat (CGI). For more than two years, the four officers shared assemblies, debates, demonstrations, friendships, and also sexual and romantic relationships with people committed to Catalan independence, the right to housing, or environmentalism.
