The Ramallo massacre occurred on September 17, 1999 in Villa Ramallo, in northern Buenos Aires Province, Argentina, when three armed robbers broke into the local offices of the Banco de la Nación Argentina, taking six hostages. After several hours, they tried to escape in a car, using the bank manager and an accountant as human shields, and holding the manager's wife. A few meters ahead, a special group of the provincial police, the GEO, killed one of the suspects and the two hostages.
