In the 1970s, Italian criminal organizations routinely kidnapped wealthy people or their children, often in the wealthy north of the country, and held them for ransom.
The most notorious example was John Paul Getty III, the grandson of oil baron John Paul Getty Senior, who was taken from central Rome and held for 5 months by the Calabrian mob in 1973. Getty's ear was cut off and mailed to an Italian newspaper to push the family into paying a ransom.
