Bitcoin theft via police impersonation: £2.1M stolen from cold storage; learn how to verify calls and protect seed phrases — read guidance from COINOTAG.
What happened in the UK Bitcoin theft by impersonation?
Bitcoin theft occurred when a scammer posing as a senior UK law enforcement officer convinced a long-term holder to enter their cold-wallet seed phrase on a sophisticated fake website, enabling the attacker to transfer £2.1 million (~$2.8M) in BTC within hours. North Wales Police are investigating recovery options.
How did the scammer gain access to the victim?
North Wales Police say the scam was “highly targeted and advanced.” The attacker contacted the victim claiming a detained person had their ID and suggested multiple security risks. Using a sense of fear and urgency, the scammer provided a link to a fraudulent site and instructed the victim to “secure assets” by entering a seed phrase.

Worried and believing they were following police instructions, the victim entered their seed phrase into a convincing fake site. The fraudsters then withdrew the entire wallet balance—estimated at $2.8 million in Bitcoin—almost immediately.
How can holders verify when contacted by “police”?
Police guidance is clear: law enforcement will never ask for a crypto seed phrase or call unexpectedly about crypto assets. Hang up on suspicious calls, use official police channels to verify claims, and never follow links or enter your seed phrase on unsolicited sites.
Why are cold-storage holders being targeted?
Criminals increasingly target long-term holders who keep large balances in hardware wallets. Cold-storage users are attractive because a single compromised seed phrase gives attackers full control of funds. Law enforcement and cybersecurity specialists note that data breaches and social engineering feed these targeted campaigns.
What are authorities saying?
North Wales Police confirm an active investigation and warn that fraudsters are evolving tactics to bypass even cautious users. The US FBI has also issued warnings about impersonation and AI deepfake voice tools being used in related scams, underlining a global pattern of threat escalation.
