What they found was not actually an illegal rave, however. Instead, police officers found a queue of pensioners, aged in their 80s and 90s, all queuing patiently to receive their vaccine shots. A world away from an illegal rave. I mean, if public services weren't as stretched as they were right now, you'd probably say it was funny.
Fortunately, the police were able to provide assistance with traffic in the area, and so it wasn't a complete waste of their time.
Apparently, the tip-off came not as the result of a hoax call, but from concerned neighbours. After a spate of illegal raves in the Essex area of late, some residents had seen an increase in traffic and assumed the worst.
