The National Crime Agency has seized a "significant quantity of cocaine" from a yacht in Newlyn harbour.
Five men were arrested on suspicion of drug trafficking in Newlyn this morning.
National Crime Agency officers intercepted the yacht and were assisted by Deep Rummage Team specialists who searched the vessel for drugs.
A Border Force team were also on hand to assist in the arrest, and investigations are currently ongoing.
The arrests come just over a month after the National Crime Agency intercepted another yacht carrying hundreds of millions of pounds worth of cocaine and escorted it into Newlyn harbour.
