Having received intelligence that an unlicensed music event might be taking place in Hackney on the night of Saturday, 23 January, officers were deployed to the area.
Shortly after 1.30am, they found an event underway in a railway arch in Nursery Road, E9. There was loud music coming from inside and it was that a significant number of people were present.
Additional resources were deployed, including public order officers, a dog unit and the police helicopter.
Numerous attempts were made to engage with organisers and others but they were uncooperative. At one point the doors were padlocked from the inside to stop police getting in.
When officers forced entry, they found an estimated 300 people packed inside the small space.
Dozens scaled fences at the rear of the arch and others forced open a gate to get away from officers.
78 people were stopped and issued with fixed penalty notices to the value of £200 for breaching Covid regulations by attending an illegal gathering.
Chief Superintendent Roy Smith, who attended the incident, said: “This was a serious and blatant breach of the public health regulations and the law in relation to unlicensed music events.
“Officers were forced, yet again, to put their own health at risk to deal with a large group of incredibly selfish people who were tightly packed together in a confined space – providing an ideal opportunity for this deadly virus to spread. Our frontline officers continue to police this public health crisis with compassion & professionalism but it is completely unacceptable they have to face such needless risks to their own health and to their families too.
“Whilst we will always seek to engage and explain, the message to those who have a total disregard for the safety of others and breach the law so blatantly is clear, our officers will act swiftly and decisively. Not just organisers, but all those present at such illegal parties can expect to be issued a fine.”
