Westchester County is turning up the heat on drug traffickers. Its newly launched effort known as Operation Pressure Point kicked off a week ago, and already officials have seized two kilos of cocaine, a .50-caliber revolver and other handguns, more than $500,000 in cash and a quantity of heroin and marijuana. Westchester's Public Safety Commissioner George Longworth says several police departments from across the County are participating including the Greenburgh Drug and Alcohol Task Force, the North Castle PD and Yorktown PD. The effort's also being spearheaded by the Internal Revenue Service and New York State Police. Said Longworth, "In this collaborative enforcement effort, we are targeting those who traffic large quantities of narcotics as well as those who distribute narcotics from outside the county for sale here in Westchester." Arrests and drug seizures have taken place along several roadways including the Hutchinson River Parkway, I287, and Route 22 in North Castle. In all, 12 suspects have been arrested since last Friday when Operation Pressure Point kicked off. Officials expect to "keep the pressure" on drug dealers and distribution efforts all Summer long.
