The Search Bloc (Spanish: Bloque de Búsqueda) was the name of three different Special Operations units of the National Police of Colombia (Policía Nacional de Colombia). They were originally focused on capturing (or killing) a particular individual or group of individuals.
The members of Search Bloc received training from the Colombian army and were specially selected for being impervious to police corruption from the drug cartels. Throughout its mission, Search Bloc faced many obstacles such as a spy within the group, allegations of collaboration with the anti-Escobar vigilante groups such as Los Pepes, which would have included vigilantism within Search Bloc pertaining to suspicious deaths of Escobar's subordinates.
Escobar was killed on December 2, 1993, in a shootout with members of Search Bloc.
