How to file a police report for crypto theft

21 September 2026

If your cryptocurrency has been stolen, you can file a police report, but you should understand what that report can and cannot accomplish. Filing a report creates an official record of the crime, may help with insurance claims or tax deductions, and in some cases can assist law enforcement in tracing funds. However, police rarely have the resources or training to recover stolen crypto, and the report itself will not reverse a blockchain transaction or force an exchange to return funds.

Before you file: what to have ready

Police will take your report more seriously if you bring organized evidence. Gather the following before you visit a station or submit an online report:

• Transaction hashes for every outgoing transfer of stolen funds. You can find these on a block explorer using your wallet address.
• The date and approximate time the theft occurred. If you discovered it later, note both the time it happened (if known) and when you noticed it.
• Your wallet address and the scammer’s wallet address (or addresses) if you identified them through blockchain tracing.
• Any communications with the scammer: emails, chat logs, social media messages, or website screenshots. If the scam involved a fake exchange, save the domain name and any registration details you can find.
• A written timeline of events: how you were contacted, what you were promised, what steps you took to send the crypto, and when you realized it was gone.

If you used a centralized exchange to send the funds, also bring your exchange account statements showing the withdrawal.

Step 1: Determine which police force to contact

You generally file a report with the police in the jurisdiction where you live, not where the scammer is located. If you are in the United States, contact your local police department or sheriff’s office. In many countries, you can also file a report with a national cybercrime unit:

• United States: FBI’s Internet Crime Complaint Center (IC3) at ic3.gov, or your local FBI field office for larger losses.
• United Kingdom: Action Fraud (actionfraud.police.uk).
• Canada: Canadian Anti-Fraud Centre or your local police.
• Australia: ReportCyber (cyber.gov.au).
• European Union: Your national police cybercrime unit.

For a small loss (under a few thousand dollars), your local police department is the most practical starting point. For larger sums, consider contacting national agencies directly.

Step 2: File the report in person or online

Many police departments accept online fraud reports, which is faster and creates an immediate record. If you file in person, call ahead to ask if they have an officer trained in cyber or financial crime. Be prepared for the possibility that the officer you speak with knows little about cryptocurrency.

When you describe the crime, use plain language. Say: “Someone tricked me into sending cryptocurrency to a wallet they control. I have the transaction records and the wallet address they used.” Avoid jargon like “rug pull,” “phishing,” or “Ponzi scheme” unless you can explain them clearly. Stick to what happened: who contacted you, what they asked you to do, and what you lost.

Provide all the evidence you collected. Ask for a copy of the report or a case number. Without a case number, the report may not be tracked or followed up.

Step 3: Understand what the police will (and won’t) do

Filing a report does not start an investigation automatically. Police prioritize cases based on the amount lost, the clarity of the evidence, and the likelihood of identifying the suspect. For a crypto theft, the path to prosecution is difficult because:

• Scammers often operate from countries with weak extradition treaties.
• Funds moved through mixers, privacy coins, or decentralized exchanges become effectively untraceable.
• Most police forces lack the tools and training to trace blockchain transactions beyond basic block explorers.

What the report can do: - Create a legal record that you were the victim of a crime. This can help if you need to claim a tax deduction for the loss (consult a tax professional). - Support a civil lawsuit if you later identify the scammer and want to sue them. - In rare cases, if the funds land on a compliant centralized exchange, the police can issue a legal request to freeze the account. This is more likely if the amount is large and the jurisdiction has mutual legal assistance treaties.

Step 4: Follow up and manage expectations

After filing, do not expect daily updates. Police departments handle many cases, and crypto theft investigations are slow. If you have new evidence - such as discovering another wallet address the scammer used - send it to the case officer with your report number.

If the police close your case without action, that is common. It does not mean you did something wrong. It means the trail went cold or the resources were not available. You can still pursue private tracing or a civil action, but those options come with their own costs and uncertainties.

What filing a report will not do

• It will not reverse the blockchain transaction. No police force can force a decentralized network to undo a transfer.
• It will not force an exchange to return your funds, unless a legal order is obtained - and even then, only if the funds are still on that exchange.
• It will not guarantee that the scammer is caught or prosecuted. Most crypto thefts never result in an arrest.

Filing a police report is a step worth taking, especially for larger losses. But it is a documentation step, not a recovery step. Treat it as one part of a broader response: secure your remaining accounts, change passwords, revoke smart contract approvals, and learn what went wrong so you can avoid the same trap again.
