An underground rave that was set to take place at an abandoned mushroom farm near Market Harborough this past weekend was restricted by police, but was still allowed to proceed until the early morning.

Authorities were tipped off by locals after party organizers turned up onsite early on Saturday and switched on a generator, which indicated to neighbors that rave activity was set to take place at the mushroom farm that's been abandoned for years. The police quickly stormed the location and shut down a few points of entry to the site, but ravers were still able to make their way to the event.

According to Harborough Mail, a police spokesman discussed what took place: “Police were made aware of an unlicensed music event in a disused premises in Welham Road, Great Bowden, during the early hours of Sunday morning. Officers attended the location and due to the number of people attending the event, believed to be up to 500, the event continued, but officers remained in the area to monitor any issues and prevent any more people from entering the premises.”

The crowd at this recent rave was severely reduced from raves that have take place at the abandoned mushroom farm in the past, but the rave was still allowed to continue with music blasting until 7AM. In October, 2016 some 2000 people attended a party at the same site.
