The organiser of a wedding faces a hefty fine after around 400 people showed up to the event.
The large gathering took place at a school in London's Stamford Hill, where the windows had been covered to stop people seeing inside.
The Metropolitan Police say that the organiser now faces a £10,000 fine.
Five other people were handed £200 penalties after police were called to the school at 9:14pm.
Detective Chief Superintendent Marcus Barnett, central east BCU commander, said: “This was a completely unacceptable breach of the law, which is very clearly in place to save lives and protect the NHS. An NHS that is under considerable pressure at a time when Covid-19 has killed nearly 100,000 people.
“This is a deadly and very dangerous disease. We can all see that and we must act responsibly.
“People across the country are making sacrifices by cancelling or postponing weddings and other celebrations and there is no excuse for this type of behaviour.
“My officers are working tirelessly with the community and we will not hesitate to take enforcement action if that is required to keep people safe.”
