Spanish police have dismantled a significant investment fraud operation that defrauded victims of over $11.8 million, arresting 21 individuals during coordinated raids across multiple cities. The scammers exploited fake investment schemes through call centers and social media, luring victims with promises of high returns and locking their funds through deceptive practices. Authorities noted the unusual presence of these call centers in Spain, which are typically based in regions with less stringent law enforcement.
