A total of 61 individuals were arrested in Barcelona, Zaragoza, Huesca, and Teruel. The group, composed of Spanish, Algerian, and Moroccan nationals, charged between 600 and 10,000 euros to help migrants bypass legal residency requirements through fraudulent means.

The network used sophisticated methods, including the look-a-like technique, where individuals resembling the clients would attend official appointments. They also created shell companies to provide fake employment contracts and social security registrations that were canceled shortly after the residency applications were submitted.

The investigation began after authorities noticed a surge in residency applications containing forged documents. The criminal structure included a wide network of collaborators who identified potential clients and managed everything from fake census registrations to fraudulent medical certificates.
