The address where police arrested a Prince George's County man on charges he operated a heroin distribution ring was incorrectly listed in the Aug. 5 editions of The Washington Post. The correct address in 2503 50th St., Tuxedo.

D.C. police yesterday arrested a 37-year-old Prince George's County man on charges that he operated a heroin distribution ring that allegedly made sales of more than $1 million a year to users in some of the city's toughest drug-dealing centers.

The suspect, Willie (Black Willie) Bullock, alledly supervised seven other men, described by law enforcement authorities as street runners, according to a federal indictment of Bullock that was filed last Friday The indictment alleged that the heroin was distributed at various locations, including 14th Street and Wallach Place NW, the 1300 block of T Street NW and the 900 block of O Street N. W. The O Street location has been a notorious drug-selling place where dealers routinely hawk their merchandise to passing motorists.

Bullock, who owns serveral luxury cars and lives in a custom-built home on a large piece of land in rurual Prince George's County, owns U.S. Racing Inc., a corporation that operates and enters cars in professional drag races throughout the country, law enforcement sources said. Bullock was arrested late yesterday afternoon at the firm's offices at 2505 50th Ave., Tuxedo.

"Man, they're been trying to get me since 1979," Bullock said yesterday while he was questioned at police headquarters in Washington. Bullock was being held late yesterday on a $50,000 bond pending an appearance today before a federal magistrate.

Law enforcement sources said evidence gathered in an 18-month investigation showed that Bullock, whom they described as a major heroin retailer, allegedly got his herion supply from sources in D.C., New York, North Carolina, California and Texas.

The grand jury indictment, which was made public Monday, charges Bullock and the seven alleged runners with conspiracy to distribute herion from January 1977 to December 1980.

The 24-count indictment also charges Bullock with three counts of distribution of herion and one acccount of operating a continuing criminal enterprise, a federal offense that upon conviction carries a minimum 10-year sentence, without possibility of parole.

The indictment alleged that Bullock attempted to evade federal taxes by filing joint returns with his wife from 1977 to 1980 that allegedly underreported the couple's combined income. Bullock's wife Ruby, a real estate agent in Prince George's County, was not indicted.

The investigation of Bullock and the seven alleged "runners" was supervised by Assistant U.S. Attorney Daniel J. Bernstein of the narcotics unit in the federal prosecutor's office here, Det. Ruben Sanchez-Serrano of the D.C. police narcotics squad and Internal Revenue Service agents.

The seven alleged "runners" charged with conspiracy are Richard (Bimbo) Benbow, Robert B. (Rob) Hagood and Andrew Johnson, all currently in prison on narcotics related charges; John L. Butler, who is in Lorton Reformatory awaiting trial on a second-degree murder charge; Lenwood E. (Linwood) Johnson of 1411 Langley Way, Langley Park; Jerry E. Duncan of 316 12th St. SE and James E. (Duke) Lewis of 628 Quebeck Pl. NW, all free on personal bond.

In addition to conspiracy, Benbow, Hagwood, Johnson and Lewis are charged with heroin distribution.
