More than 100 ravers flouted coronavirus restrictions as they crammed into a London squat despite the city’s infection rate continuing to rise.
Police and council chiefs have warned the tougher measures may follow unless more people abide by social distancing and household mixing rules.
Video of the party shows more than 100 people dancing on Saturday as a DJ plays at the top of a flight of stairs in an undisclosed location.
None are wearing masks or observing social distancing.
The drum and bass party lasted around an hour, although the venue was full at its peak with many shut out, as posts and images on Instagram suggest.
On the DnB Rollers page, one reveller wrote: ‘Was sick while it lasted.’
Another said: ‘Looks like it was an amazing night!
‘Big up to the organisers who had the balls to put quality of life first!’
However, another contributor replied: ‘Definitely not the time to be doing s*** like this yet.
‘Not only is it making it drag on longer for the people who are actually sticking to the rules but it’s putting lives at risk. Bit selfish really.’
London’s Covid-19 infection rates began rising during the second lockdown in mid-November.
London had 191.8 cases per 100,000 people for the week of November 30 to December 6 – up from 158.1 per 100,000 the previous week
Mayor Sadiq Khan said: ‘If we don’t all work together now, we may face tougher restrictions across the capital.’
Cllr Georgia Gould, chair of London Councils, told the Evening Standard vigilance levels will be heightened for what is expected to be a busy Christmas shopping weekend.
‘We will be working with the Metropolitan Police to make sure that everyone knows the rules and enforcing them to protect everyone from coronavirus,’ she said.
London is currently in tier two ahead of the Government’s review of each area on December 16.
Metro.co.uk told in November how ravers were switching tactics during the lockdown, including using cheap kit known as ‘suicide rigs’ to reduce losses if gear is seized by police.
Under legislation introduced in the summer, organisers of illegal raves, unlicensed music events or any other unlawful gathering of more than 30 people face fines of up to £10,000.
Those attending can be fined £200, which is doubled if they repeat the offence up to a maximum of £6,400.
