Border Patrol agents arrested a man who they said tried to float from Mexico to the U.S. on a duffel bag filled with marijuana.

Agents said Monday the man was stopped about a mile north of the border near San Diego after they heard reports Sept. 19 of someone swimming late at night in the Pacific Ocean.

The agents said the 55-year-old man was floating about 600 yards from shore.

The man told agents he was from Mexico, and he was taken into custody.

Agents said they found a little more than 52 pounds of pot inside the bag.

The marijuana was worth more than $23,000, agents said.
