What to do if…
you receive repeated unwanted messages that suddenly become threatening

Short answer

If you think the person might act soon, knows where you are, or you feel in immediate danger, call 999 now. Otherwise, stop engaging, keep the messages, and report it to police (101 or online) as soon as you can.

Do not do these things

  • Don’t reply “just to calm them down” or to argue your case — it can escalate things and creates more openings for contact.
  • Don’t agree to meet them, “talk it out,” or prove anything in person.
  • Don’t delete the messages or the account/thread in panic.
  • Don’t post screenshots publicly (it can inflame the situation and can expose your details).
  • Don’t click links, open attachments, or download files they send — even if it looks “important.”
  • Don’t rush to change your number or wipe your accounts before you’ve reported and saved what you need.
  • Don’t assume “it’s only online” — treat escalation as real-world safety information.

What to do now

  1. Get to a safer pause (right now).
    If you’re alone, move somewhere you feel safer (a room with a lock, a public place, a neighbour/friend). Tell one trusted person what’s happening and ask them to stay reachable. If you’re at work/school, let reception/security know you’re being threatened and ask them not to confirm your presence to anyone.

  2. Decide if this is an emergency.

    • Call 999 if you believe there’s immediate risk (for example: threats to come “now,” threats to kill, they’re nearby, they know your address and you’re scared they’ll show up, or you feel unsafe to stay where you are).
    • If it’s not immediate danger, call 101 or report online to your local police force as soon as possible.

  3. If you can’t speak safely, use the UK “silent 999” option.
    Call 999 anyway. If you can’t speak, stay on the line and follow the operator’s prompts — you may be asked to press 55 to confirm it’s a real emergency. If you need to text 999, this typically requires pre-registration with the emergency SMS service (so don’t assume it will work if you haven’t set it up already).

  4. Preserve what you already have (without spiralling into “perfect evidence”).
    You don’t need everything neatly packaged before you report — don’t delay reporting to “get it perfect.” Do, however:

    • Keep the full message thread(s) and any voicemails/voice notes.
    • Take clear screenshots that show the sender, date/time, and the threat.
    • Write a short log: when it started, how it escalated, any key threats, and whether they know your address/workplace.

  5. Make it harder for them to reach or find you (without wiping your digital trail).

    • Turn off location sharing in the relevant app(s) and review who can see your posts/stories.
    • Tighten privacy settings and remove personal details that help someone locate you (address, workplace, school, routine).
    • If you share a home with others, tell them not to engage with the sender and not to confirm details about you.

  6. Report the account/messages to the platform and (if relevant) your mobile network.
    Use the in-app reporting tools for threats/harassment. If it’s SMS/calls, report it to your mobile network too. If you plan to block, save screenshots first so you don’t lose access to the thread.

  7. Use specialist support alongside police reporting when it fits the pattern.

    • If this feels like stalking/fixation (persistent, intrusive, escalating), you can contact the National Stalking Helpline (Suzy Lamplugh Trust) on 0808 802 0300.
    • If the sender is a current/former partner or family member, you can contact the National Domestic Abuse Helpline on 0808 2000 247 (24/7).

  8. When you report, be explicit about the escalation and what you’re scared might happen next.
    Use plain language: “This started as unwanted messages and has now become threatening. I’m worried they will do X.” Ask for the safest way for police to contact you if you’re worried about being called back at home or in front of others.

What can wait

  • You do not need to decide right now whether you want “charges,” a formal statement, or court action.
  • You do not need to immediately change your number, delete accounts, or move home.
  • You do not need to confront them, warn them, or “explain” anything.
  • You can sort out longer-term digital security and boundaries after you’ve reported and you’re safe.

Important reassurance

It’s common to feel shaky, distracted, or embarrassed when a message tone flips into threats — that reaction doesn’t mean you’re overreacting. Treating escalation seriously and asking for help early is a protective step.

Scope note

This is first steps only: immediate safety, preserving information, and getting the right support in motion. Later options can be discussed once you’re safer and supported.
