Department Narcotics Bureau detective Sonny Grosso has stated that the kingpin of the French Connection heroin ring during the 1950s into the 1960s was Corsican Jean Jehan. Although Jehan is reported to have arranged the famous 1962 deal gone wrong of 64 pounds of "pure" heroin, he was never arrested for his involvement in international heroin smuggling. According to Grosso, all warrants for the arrest of Jehan were left open. For years thereafter, Jehan was reported to be seen arranging and operating drug activities at will throughout Europe. According to William Friedkin, director of the 1971 film The French Connection, Jehan had been a member of the French Resistance to Nazi Occupation during World War II and, because of that, French law enforcement officials refused to arrest him. Friedkin was told that Jehan died peacefully of old age at his home in Corsica. The 1970s: Dismantling Following five subsequent years of concessions, combined with international cooperation, the Turkish government finally agreed in 1971 to a complete ban on the growing of Turkish poppies for the production of opium, effective June 29, 1971. During these protracted negotiations, law enforcement personnel went into action. One of the major roundups began on January 4, 1972, when agents from the U.S. Bureau of Narcotics and Dangerous Drugs (BNDD) and French authorities seized 110 pounds (50 kg) of heroin at the Paris airport. Subsequently, traffickers Jean-Baptiste Croce and Joseph Mari were arrested in Marseille. One such French seizure from the French Connection in 1973 netted 210 pounds (95 kg) of heroin worth $38 million. In February 1972, French traffickers offered a United States Army sergeant $96,000 () to smuggle 240 pounds (109 kg) of heroin into the United States. He informed his superior who in turn notified the BNDD. As a result of this investigation, five men in New York and two in Paris were arrested with 264 pounds (120 kg) of heroin, which had a street value of $50 million. In a 14-month period, starting in February 1972, six major illicit heroin laboratories were seized and dismantled in the suburbs of Marseille by French national narcotics police in collaboration with U.S. drug agents. On February 29, 1972, French authorities seized the shrimp boat, Caprice des Temps, as it put to sea near Marseille heading towards Miami. It was carrying 915 pounds (415 kg) of heroin. Drug arrests in France skyrocketed from 57 in 1970
