Covid: Hackney Railway Arch Rave Attended By ‘300 People’
The title of this post, is the same as that of this article on the BBC.
This is the introductory paragraphs.
Police have issued more than £15,000 in fines after 300 people attended an illegal rave in a railway arch.
Officers raided an unlicensed music event in Nursery Road, Hackney, at 01.30 GMT on Sunday.
Sounds to me, that the safest way to handle this number of ravers, is to use a water cannon, firing smart water, so they can be identified for a couple of weeks.
