U.S. Customs and Border Protection says officers discovered a concealed firearm suppressor at John F. Kennedy International Airport in New York has led to the seizure of a cache of firearms in neighboring Connecticut. 

The agency reported the case Tuesday. 

Officers assigned to the airport's international air cargo operations identified an inbound shipment from Hong Kong as "high risk" for possible contraband found the suppressor, which the agency said was "falsely declared as automotive equipment." 

The seizure and follow-up investigation led authorities to identify Alexander Oranzo, 46, of Branford, Conn., as the alleged intended recipient.

The investigation led to one arrest and the seizure of 39 firearms, explosives and other contraband. Oranzo was arrested at his home where the cache was purportedly found. A search warrant was executed at the home April 27.

In addition to the firearms, law enforcement found Tannerite, a brand of explosive consisting of ammonium nitrate and aluminum powder. It's designed to explode when hit by high-velocity bullets and helps with target practice. Officers also discovered 58 high-capacity magazines, five suppressors, three sets of body armor, ammunition and narcotics. 

Oranzo was charged in total with over 100 crimes, including criminal possession of a firearm, possession of more than five ounces of marijuana, and possession of a sawed-off shotgun.
