Roberto Calvi, alias "God's Banker" ("Il banchiere di Dio") in charge of "Banco Ambrosiano", whose main-shareholder was the Vatican Bank, was killed in London on 18 June 1982. Banco Ambrosiano, which crashed in one of the major financial scandals of the 1980s, was involved in money-laundering activities for the Mafia and allegedly in funneling funds to the Polish Solidarity trade union ("Solidarność") and the Contras in Nicaragua. Ernesto Diotallevi, one of the leaders of the "Banda della Magliana", is being prosecuted for Calvi's murder.
