Around 360kg of cocaine with a potential value of £50 million has washed up on two beaches in Norfolk in England.
The National Crime Agency (NCA) said a number of holdalls were found at Hopton-on-Sea yesterday, and a "small number of packages" were discovered at Caister-on-Sea today.
A member of the public spotted the bags and police are now looking for more that could be in the area.
Matthew Rivers, from the NCA's border investigation team, said: "We are now working with Border Force, the Coastguard Agency and Norfolk Police to try and establish how the bags ended up where they did; however, it is extremely unlikely that this was their intended destination.
"This is obviously a substantial seizure of class A drugs, and its loss will represent a major blow to the organised criminals involved."
Superintendent Dave Buckley, of Norfolk Police, said: "We are assisting the National Crime Agency with their searches and while we believe we have recovered all the packages, should any member of the public find one they are urged to contact Norfolk Police immediately on 101.
"We will have extra officers in the area to monitor the situation."
