During the pandemic, Britain imposed strict restrictions on crowds.
Current laws stipulate that only six people may meet outdoors.
After the police received a tip about the party, they went to the scene by drone and helicopter, equipped with thermal cameras.
When the participants saw the lights, they fled, whereupon the police were ready to stop them on their way there.
22 people were fined £ 200.
According to the police, the person who arranged the party risks a fine of up to as much as 10,000 pounds, writes BBC.
