Philadelphia Airport Cocaine Bust Is Largest In Airport History (VIDEO)

Customs officials at Philadelphia International Airport seized a 130-pound cache of cocaine valued at $4 million Sunday.

The drugs were found in three unattended duffel bags. It's believed this is the biggest cocaine bust the airport has seen, according to records going back to 1990, reports MyFox Philly. The largest seizure on record is 55 pounds in 2000.

"The volume alone raises concern for us. Customs and Border Protection officers remain steadfastly vigilant to stop narcotics here at our border before it can hurt our families and our communities," said Allan Martocci, U.S. Customs and Border Protection (CBP) Port Director for the Area Port of Philadelphia.

The duffel bags, which arrived on a flight from the Dominican Republic, were picked up by CBP after passengers had left the international terminal, reports ABC Philadelphia. A drug-sniffing dog detected they might contain narcotics.

When officers unpacked the bags, they discovered 52 bricks wrapped in blankets. A field test confirmed the presence of cocaine.

No arrests were made.
