An Egyptian national has pleaded guilty after he kicked a customs dog so hard it became airborne at a Washington, DC area airport, authorities say.

Hamed Ramadan Bayoumy Aly Marie, 70, pleaded guilty to kicking Freddie the Beagle, who was working with US Customs and Border Protection (CBP) to detect smuggled agricultural products at Washington Dulles International Airport.

Authorities say he kicked the dog after it allegedly detected over 100lb (45kg) of prohibited food products in his luggage.

Marie was ordered to pay for Freddie's veterinarian bills and was deported back to Egypt.

The incident unfolded early on Tuesday in the baggage claim area of the airport, which is located just outside of Washington in Virginia.
