Spanish National Police have dismantled a sophisticated SIM swapping criminal network operating from Barcelona and L’Hospitalet, arresting five individuals in coordinated raids this week.
Authorities seized substantial evidence including luxury watches, perfumes, and 54 SIM cards used to systematically drain victims’ bank accounts. The operation highlights the escalating threat of SIM-based financial fraud in urban centres.
Modus Operandi
Criminals employ SIM swapping by deceiving telecommunications providers into issuing duplicate SIM cards. Once activated, these cards enable immediate access to victims’ banking services.
Investigators recovered 29 mobile phones utilised for banking operations and documented the gang’s use of disguises during ATM withdrawals. The group possessed personal data for 542 bank customers awaiting targeting.
This case follows last week’s arrest by Mossos d’Esquadra of a 21-year-old in Martorell for voice phishing fraud. That separate scheme resulted in six victims losing more than €11,000.
Broader Implications
These arrests demonstrate organised criminal activity within Barcelona’s metropolitan area. The Generalitat de Catalunya has issued repeated warnings about increasing financial fraud incidents.
Police discovered counterfeit identification equipment and an extensive database of potential victims during their investigation. The network operated nationally while maintaining its base in Barcelona.
Financial institutions never contact customers requesting urgent money transfers. Consumers should implement two-factor authentication methods that do not rely exclusively on mobile numbers.
