Coast Guard crews unloaded nearly two tons of cocaine in Miami Beach on Friday, after a big bust at sea.

Four men were arrested.

The drugs were captured in a mid-sea drug seizure in the Caribbean Sea on March 3rd in the middle of the night.

The vessel maneuvered to avoid Coast Guard authorities, until airborne marksmen shot out the engines.

Crew from the Coast Guard's Northland Cutter spotted an open air boat from a chopper, and on board, 3500 pounds of cocaine.

Each bail of cocaine weighs between 55 and 70 pounds.  All of the bricks inside are about 2 pounds each, individually wrapped in plastic.  There are anywhere from 20 to 30 bricks inside each bail.

Thousands of pounds and millions of dollars in illegal white power, now off the streets, in the hands of the feds.

The four men on board are now in custody of the U.S. Department of Justice.

The Coast Guard said it is not known where the men were coming from or going with the cocaine.
