They did not comply with covid restrictions. They looked for holiday lets in rural Catalonia where they could organise huge parties with about 300 or 400 participants. The landlords were led to believe they were renting the houses to families, and were then left out of pocket as no payment was made for the rental. The organisers did not pay for material they rented either, nor for catering and beverage services: all the invoices remained outstanding. The organisers of these covid parties did, however, charge for admission and also for the drinks. The Mossos d'Esquadra have arrested three people who formed a criminal group which, according to the police, had seen an opportunity in the middle of the pandemic and organised these illegal parties. They are estimated to have defraud around €200,000.
