Ships from France and the UK stop a big oil boat. This boat is a Russian oil tanker. It is in the sea.
The boat goes to a port in France. It is checked for breaking rules. The police say the boat name is 'Grinch'. They do not know its country.
French and UK boats and helicopters help. Soldiers get on the boat. The 'Grinch' boat came from Russia. It is going to France.
This boat might help Russia sell oil. It hides from rules. This is because Russia hurt Ukraine.
The boat uses a flag from a small country. It might be under UK rules too. The police want to know who owns it. They are looking for answers.
