A little context: On May 9, 1978, Catalan businessman José María Butló (born 1900) was kidnapped by members of the Exèrcit Popular Català (Catalan Popular Army,) and the terrorists attached a bomb to his chest. They told him that if he did not pay 500 million pesetas they would detonate the bomb. Also, if he tried to remove the bomb, it would explode. Details are sketchy, but we know he refused to pay and, later, when he was at his home, the bomb exploded. He died.
