Greece Busts Bonus Hunter Gang: 43 Suspects and a “Ninja-Style” Arsenal

Greek law enforcement authorities have broken up a large criminal network accused of systematically defrauding licensed online bookmakers through coordinated bonus abuse schemes. The case, first reported by Proto Thema, involves 43 suspects and an operation that investigators say had been running for years.

Scheme Built on Arbitrage and Repeated Bonus Claims

According to police findings, the group relied on arbitrage strategies combined with aggressive bonus hunting tactics. By carefully placing calculated wagers across different outcomes, participants were able to lock in returns regardless of how sporting events concluded.

To maximize profits, members allegedly registered hundreds of user accounts using the personal details of third parties. Creating accounts under different identities enabled them to repeatedly claim welcome rewards intended strictly for new customers.

Authorities estimate that the illegal proceeds exceeded €1.5m, while financial damage to operators surpassed €120k.

A Web of Linked Profiles

What initially looked like scattered accounts soon turned out to be tightly connected. Investigators say many of the profiles shared the same digital fingerprints, login patterns, and timing, making it clear they were controlled as part of a single plan.

The trail leads back several years. Authorities are convinced the activity began no later than early 2020 and continued quietly in the background, expanding step by step instead of appearing as a one-off incident.

Money, Phones and High-End Vehicles Recovered

Searches carried out at multiple properties uncovered significant evidence. Officers seized more than €19k in cash, access details connected to over 700 accounts, more than 500 SIM cards, and upwards of 200 mobile devices believed to have been used in the scheme.

Five luxury cars were also taken into custody. Prosecutors suspect the vehicles were bought with proceeds generated through the operation.

At two residences, police additionally found a handgun along with ammunition, a discovery that broadened the scope of the case beyond financial misconduct.

Serious Criminal Charges Filed

The individuals involved now face a wide range of charges, including participation in and leadership of a criminal organization, fraud, document forgery, violations of gambling regulations, and money laundering.

Officials in Greece say this case shows how far these schemes have evolved. What once looked like isolated abuse of welcome offers is now turning into coordinated group activity, with participants carefully planning their moves and learning how to stay under the radar for years.

Not long ago, we also reported on a similar case in the United States, where two bonus hunters were arrested for setting up multiple accounts to exploit promotional offers.
