UNITED NATIONS — A shipment containing 16 kilograms of cocaine was seized last week at the U.N.’s mail intake center, a New York Police Department spokesman said Thursday.

Paul Browne, NYPD’s chief spokesman, said the drug was in a white bag evidently masquerading as a diplomatic pouch that raised suspicions when it was being scanned because it was stamped with what looked like a poorly concocted version of the U.N. logo.

Browne said here was no name or address on the shipment sent from Mexico City through Cincinnati.

U.N. security officials called the NYPD and Drug Enforcement Administration, which confirmed the substance inside the shipment intercepted Jan. 16 was cocaine, the police spokesman said.

U.N. undersecretary-general for safety and security Gregory B. Starr told reporters Thursday evening that “there is nothing to indicate that this had anything to do with anybody at the United Nations.”
