A man from Witney is due to appear in court following a mass gathering at a warehouse in South Gloucestershire last year.
Hundreds of people attended the Halloween event in Yate on Saturday 31 October, which was a breach of the Covid-19 restrictions in force at the time.
Avond and Somerset Police say they prevented between 200 and 300 more people reaching the site.
Two people received £10,000 fines in the days after the event for their part in organising it and a further 13 people have been retrospectively fined £200 for attending a large gathering.
