Comment la police irlandaise a récupéré 500 bitcoins que l'on pensait perdus à jamais

[kim]

Irish authorities have regained access to a Bitcoin wallet long considered permanently locked, in a rare development that challenges assumptions around lost private keys.

The Criminal Assets Bureau confirmed it had seized a wallet containing 500 Bitcoin, now valued at more than $35 million.

The funds were linked to a convicted drug dealer and had remained inaccessible for years after the access codes were believed to be lost.

The recovery was supported by Europol’s European Cybercrime Centre, which provided technical expertise and coordinated efforts across jurisdictions.

Role of Europol support

The Criminal Assets Bureau said it gained access to the wallet with assistance from Europol, which hosted operational meetings at its headquarters in The Hague.

The agency also provided advanced technical expertise and decryption resources to investigators and analysts.

Authorities described the process as highly specialised, requiring coordination between law enforcement and cyber experts.

Such cases typically involve detailed forensic work, especially when access credentials are no longer available.

Origin of lost Bitcoin holdings

The recovered wallet is part of a larger set tied to Clifton Collins, who was sentenced to five years in prison for growing and selling cannabis.

According to reports from the Irish Times, Collins purchased around 6,000 Bitcoin between late 2011 and early 2012 using proceeds from his drug operation.

He stored the private keys on a single sheet of A4 paper hidden inside the aluminium cap of a fishing rod case at his rental property.

Following his arrest in 2017, the property was cleared by the landlord, and the belongings were discarded.

Collins later claimed the fishing rod case had been stolen before this took place.

The disappearance of the keys meant the funds were initially believed to be permanently inaccessible.

Blockchain data and wallet movement

On Tuesday, blockchain intelligence platform Arkham flagged activity from a wallet labelled “Clifton Collins: Lost Keys.”

The wallet transferred 500 Bitcoin to Coinbase Prime, marking its first movement in more than a decade.

Arkham data shows Collins is linked to 14 addresses with combined holdings of around 5,500 Bitcoin, valued at over $391 million.

The recent transfer indicates that at least part of these holdings is now accessible.

The movement also highlights how blockchain transparency allows analysts to track activity even when access to wallets has been lost.

Rare case of crypto recovery

In most cases, losing a Bitcoin private key results in permanent loss of funds due to the design of public key cryptography.

Without the correct credentials, access is not possible, and recovery is generally considered unfeasible.

This case stands out because authorities were able to regain control of assets once thought unreachable.

It shows how advances in technical capabilities and cross-border cooperation are shaping the way law enforcement approaches cryptocurrency investigations.

According to The Guardian, Collins was arrested in 2017 after police searched his car and found cannabis.

Despite efforts to distribute his holdings across multiple wallets, a portion of the assets has now been successfully accessed and seized.
