The streets of New York City are a little bit cleaner today after the NYPD broke up a drug ring in Harlem known as the "Kings of Dust" for its expertise in trafficking PCP, better known in eras of bygone popularity as "angel dust." Thirty-five members of the group, which was based in public housing at East 117th Street and Madison Avenue, were busted and charged in a 268-count indictment yesterday after a fifteen-month investigation, in which officials said they witnessed the use of an 8-year-old boy as a lookout. In the home of the suspected kingpins, police discovered $39,000 in cash and 2.5 gallons of PCP in Hawaiian Punch bottles. "Now that is a lot of PCP," said Police Commissioner Ray Kelly.
