A Northwest Washington man and two New York men were arrested yesterday and charged with narcotics violations after police broke up a suspected drug transaction and recovered about $6,000 cash, two handguns and cocaine with a street value of about $10,000, D.C. police reported.

They said the arrests occurred about 8:15 a.m. when three uniformed officers from the 3rd District narcotics enforcement unit, on patrol in a police cruiser, noticed a car with three persons inside parked diagonally in an alley in the 1400 block of W Street NW.

One of the car's occupants ran and was chased to a fourth-floor apartment at 1418 W St. NW, where he banged on the door and forced his way inside, police said. They said three children and their parents were able to get out of the apartment without incident, after which a suspect surrendered to police.

Police said they recovered two handguns and a small bag with about 40 grams of cocaine, much of it uncut, that the fleeing man allegedly had dropped during his flight.

Alberto King Jr., 29, of 1630 Park Rd. NW was arrested at the apartment and charged with first-degree burglary, possession of cocaine with intent to distribute, carrying a pistol without a license and possession of unregistered ammunition.

Police said two men were arrested in the alley and charged with possession of cocaine with intent to distribute. They were identified as Marino Herrera, 21, and Josue Vasquez, 25, both of Manhattan.
