MIAMI-DADE COUNTY, Fla. — A 23-year-old man was arrested over the weekend on a drug trafficking charge after authorities said he tried to travel from Miami to London with a whopping 75 pounds of marijuana in his luggage.

According to an arrest report from the Miami-Dade Sheriff’s Office, Harrison O’Neill Tiernan, of Austin, Texas, was arrested Saturday afternoon at Miami International Airport after checking two suitcases for his British Airways flight to London’s Heathrow Airport.

U.S. Customs & Border Protection officers notified MDSO after inspecting both suitcases and discovering they contained multiple vacuum-sealed packages containing “green leafy” substances, the report stated.

CBP officers said Tiernan was stopped while trying to board the flight and acknowledged that the two checked bags belonged to him.

An MDSO deputy then responded to the scene and Tiernan was taken into custody.

The drugs, later confirmed to be about 75 pounds of marijuana, were confiscated and impounded as evidence.

Deputies said after his arrest, Tiernan stated that he would need to speak with his attorney and requested to know details about his bond amount.

As of Monday afternoon, he was being held at the Metrowest Detention Center. Online jail records listed his bond as “to be set.”
