Spanish Police Arrest Five in Cross-Border Crypto Kidnapping and Killing Case
Spanish police have arrested five people in Spain and charged four more in Denmark following a cross-border investigation into the kidnapping and killing of a man targeted for his cryptocurrency holdings, authorities said on Thursday.
The case, involving violent coercion to access crypto wallets, has raised fresh concerns about the growing physical risks faced by individual crypto holders.
Masked Gunmen Target Crypto Holders in Málaga
The investigation began in April after a woman reported to police in Málaga that she and her partner had been abducted in the nearby town of Mijas.
According to investigators, the couple was ambushed by three or four masked men dressed in black and armed with handguns. When the man attempted to escape, he was shot in the leg, police said.
Both victims were forced into a vehicle and taken to a house, where they were held for several hours. During their captivity, the attackers tried to gain access to the couple’s cryptocurrency wallets.
The woman was released around midnight. Her partner did not survive. His body was later found in a wooded area, showing signs of violence in addition to the gunshot wound, authorities said.
Weapons Seized, Suspects Charged Across Two Countries
As part of the investigation, Spanish police carried out six raids on properties in Madrid and Málaga, seizing two handguns — one real and one imitation — along with a baton, blood-stained clothing, mobile phones, and documents linked to the crime. Investigators also recovered biological evidence tied to the scene.
In Denmark, authorities charged four suspects in connection with the case. Two of them were already serving prison sentences for similar crimes, according to police.
Officials described the suspects as part of a coordinated criminal group operating across borders and targeting victims with digital assets.
“Wrench Attacks” on Crypto Holders Are Rising
The case underscores a troubling trend in the crypto world: physical attacks designed to force victims to hand over access to their digital wallets, commonly known as “wrench attacks.”
According to blockchain analytics firm Chainalysis, these attacks are on pace to hit record levels in 2025. As of July, 35 incidents had already been reported worldwide, putting the year on track to surpass the peak seen during the 2021 bull market.
Chainalysis noted that crypto crime is increasingly moving offline. More than $2.17 billion has been stolen from crypto services so far this year — already more than in all of 2024 — with nearly a quarter of losses now linked to personal wallet attacks.
Bitcoin holders are being hit especially hard, as criminals increasingly target high-value wallets. The Asia-Pacific region has emerged as one of the most affected areas, with countries such as Japan, Indonesia, South Korea, and the Philippines reporting a rise in violent incidents.
A Growing Security Warning
For many in the crypto community, the case serves as a stark reminder that security risks are no longer limited to hacks and scams. As adoption grows, authorities and industry experts are urging holders to rethink personal safety, privacy, and how they store and access their digital assets.
