This is the moment a member of the US Coast Guard jumped on to a semi-submerged submarine suspected of smuggling drugs into America.
In the dramatic video, the coast guard is seen tracking the submarine off the coast of San Diego in the Pacific Ocean.
The coastguard shout for the boat's crew to stop. After the vessel fails to come to a stop, a member leaps from his boat on to the submarine and banged on the hatch. The sub was carrying more than seven tonnes of cocaine.
The raid, which took place on June 18, was part of a series of drug seizure operations that netted a total of 18 tonnes.
