Leonardo Bertulazzi, a former member of the Marxist guerrilla group the Red Brigades, was about to be extradited to his home country of Italy. Leonardo Bertulazzi used a harness to abseil down from a fifth-floor balcony in the capital, Buenos Aires. His escape was not immediately registered because he had tampered with his electronic ankle monitor so that it continued to transmit body temperature measurements even after he had prised it open.
