What to do if…
you suspect someone is impersonating law enforcement or an official authority to intimidate you

Short answer

Create a safe pause and verify independently: if you feel at risk right now, call 999; otherwise stop engaging and call 101 (using a number you find yourself) to check whether they’re genuine.

Do not do these things

  • Don’t let them inside, follow them, or get into a vehicle “to sort it out” just because they sound official.
  • Don’t hand over cash, bank details, one-time codes, gift cards, crypto, or your phone “for checking”.
  • Don’t call back a number they give you, or click links they send, even if the caller ID looks real.
  • Don’t show identity documents through an open doorway or share personal details “to confirm you”.
  • Don’t argue or try to “catch them out” if you feel unsafe — prioritise distance and verification.

What to do now

  1. Get to a safer pause. If they’re at your door, keep the door locked. If you’re outside, step into a public, well-lit place with other people nearby.
  2. If you feel threatened or a crime may be in progress, call 999. Say: “I think someone is impersonating an officer/official and intimidating me. I’m at [location].”
  3. If it’s not an emergency, stop the conversation and call 101 to verify. Tell the operator what the person claims (force/agency name), where you are, and what they want. Use a number you find yourself (not one they give you).
  4. If they claim to be from a national agency, use that agency’s official officer-verification route. For example, the National Crime Agency provides an officer verification contact page. Use only contact details you look up independently.
  5. If they’re in person and you can do so safely, ask for ID without opening the door/closing distance. For police, ask to see a warrant card and note: name, warrant/shoulder number, force, and what they say the purpose is. Keep physical distance.
  6. If it’s on the phone/text/email: end contact and preserve what you can. Screenshot messages, note the time, the number/email, any “reference numbers”, and exactly what they demanded or threatened.
  7. Report it through the right route:
    • Immediate risk / in-progress incident: report via 999.
    • Non-emergency suspicious impersonation/intimidation: report via 101 (or your local force’s online reporting).
    • If it involved fraud/cyber crime (demands for money, bank details, account access): report to Report Fraud (England, Wales and Northern Ireland) online or by phone.
    • If you live in Scotland or the incident happened there: report via Police Scotland (101 for non-emergency; 999 in an emergency).
  8. If they obtained anything sensitive, take one “containment” step now. For example: contact your bank using the number on your card/app; change the password for the account they targeted; and turn on two-step verification — but only after you’re safe and the person is no longer present.

What can wait

  • You do not need to decide right now whether to make a formal statement, press charges, or pursue a case.
  • You do not need to prove it was fake before calling 999/101 — “I’m not sure and I’m scared” is enough.
  • You can sort out longer reports, screenshots, and any account clean-up after you’re safe and calm.

Important reassurance

People who impersonate authority rely on shock and urgency. Feeling rattled, frozen, or unsure is a normal stress response. The safe move is to slow everything down and verify using numbers and channels you find independently.

Scope note

This is first-steps guidance to keep you safe and prevent irreversible mistakes. Depending on what happened (money taken, threats made, in-person attempt), you may later want specialist support from police, victim support services, or a trusted adviser.

Important note

This guide is general information, not legal advice. If you believe you’re in immediate danger, call 999. If you’re unsure, prioritise safety and independent verification over cooperating with any on-the-spot demands.
