U.S. Says It Disrupted Major Heroin-Importing Operation in Bronx

But it was not the largest amount ever intercepted in the city. In the late 1960s and early 1970s, two shipments of more than 200 pounds each were seized from cars aboard passenger ships entering the city. In 1989, federal agents uncovered 849 pounds of heroin in Flushing, Queens, and in 1991, 1,071 pounds was found in Oakland, Calif.
After the Suburban returned to the Bronx and was parked behind the apartment building, a drug-sniffing dog detected narcotics in it.
Because of an editing error, a headline with an earlier version of this article misstated where law enforcement officials found 155 pounds of heroin. It was in a vehicle, not an apartment.
