You are in Northern Ireland and the person doing this is in Australia. You report at home, and at the same time trigger action where they actually are.
999 (also 112 works across the UK/EU and routes to the same emergency operator). Use when a crime is in progress, there is an immediate threat to life or safety, or a suspect is nearby.
Most people here are not in an active emergency. To start an official record, use the non-emergency steps below.
Keep doing everything below in Northern Ireland. At the same time, the fastest leverage often sits in Australia, where the person actually is.
The fastest protection lever against a perpetrator located in Australia is the eSafety Commissioner's civil removal scheme under the Online Safety Act 2021. eSafety can issue REMOVAL NOTICES to platforms and end-users under the Adult Cyber Abuse Scheme (18+), the Image-Based Abuse Scheme, the Cyberbullying Scheme (under-18) and the Online Content Scheme; non-compliant services can face civil penalties of up to 500 penalty units. For most schemes the victim must first report to the platform or service, then lodge at https://www.esafety.gov.au/report. This is a civil takedown route that runs alongside, and does not replace, a criminal police report. Note the deliberately high 'serious harm' threshold for the Adult Cyber Abuse Scheme. In parallel, where the victim fears ongoing harm, an Apprehended Violence Order (AVO) / personal safety intervention order can be sought against a locally-located perpetrator via the local court or police.
When the perpetrator is located in Australia and the victim is overseas, the foreign victim's own police refer the matter to Australian law enforcement through police-to-police channels: the foreign country's INTERPOL National Central Bureau contacts the AFP-hosted INTERPOL National Central Bureau (NCB) Canberra (within AFP International Operations, operating 24/7), which channels notices, information-sharing and assistance requests. The matter is then assessed and, for an individual harassment case, typically referred to the relevant Australian state or territory police where the perpetrator is located. For evidence-gathering or prosecution that needs formal cooperation, a Mutual Legal Assistance (MLAT) request is coordinated by the Commonwealth Attorney-General's Department under the Mutual Assistance in Criminal Matters Act 1987. A victim cannot trigger these channels directly; they ask the investigating police to route the matter through INTERPOL Canberra or MLAT.
eSafety is a civil regulator and does not prosecute, award damages, or replace police. The criminal route remains state/territory police (or the AFP for serious/transnational matters), reachable from abroad only via the police-to-police INTERPOL Canberra channel described above.
File a non-emergency report, and do the single most important thing: get your report / reference / occurrence number. That number is the key that unlocks platforms, prosecutors, employers and protective orders.
The primary way to START AN OFFICIAL PAPER TRAIL for non-emergency online harassment, stalking, threats, etc. Available 24/7. Select the incident type (e.g. report a crime, hate crime, anti-social behaviour), enter details and evidence, and you receive a confirmation/record with an incident number. PSNI has taken tens of thousands of reports through this channel since September 2023 (roughly 36,874 online reports between 1 Sep 2023 and 17 Jan 2025). Pair it with the 'My PSNI' portal victim-update facility to track the investigation. Keep the reference number for follow-up and escalation.
Call 101 to report a non-emergency crime or incident and create an official occurrence/record with a reference number. Use when you want to speak to an operator, the matter is not an emergency, and you want it logged. For hate crime, callers are directed to '101 option 2'. Always use 999 instead if there is an immediate threat.
If the harassment is motivated by hostility to a protected characteristic, you can use the True Vision online reporting form, which is sent immediately to PSNI and generates a police record. Run by the National Police Chiefs' Council. Useful as an alternative intake that still lands with PSNI.
File here in addition to, not instead of, your local police report.
INTAKE / TRIAGE, NOT a police force. National reporting centre for fraud and cyber crime for England, Wales AND Northern Ireland (Scotland uses Police Scotland 101 instead). Reports are assessed by the National Fraud Intelligence Bureau (run by the City of London Police) and, where there are viable leads, disseminated to the relevant local force (PSNI in NI) for investigation. It does not investigate cases itself. Use it specifically for fraud, identity fraud, scams, hacking/computer misuse, and extortion involving money. A live cyber attack in progress should be reported by phone immediately. Report Fraud went live on 4 December 2025 (replacing Action Fraud), with Action Fraud traffic redirecting over the following months and full public launch in January 2026; the phone number is unchanged from Action Fraud.
Investigates the most serious, organised and cross-border cyber crime across the whole UK including Northern Ireland; it is the UK's lead agency against serious and organised crime, including cybercrime that crosses regional or international borders. The public does not normally report individual harassment cases directly to the NCA (those go to PSNI / Report Fraud); the NCA takes the high-harm, organised, or cross-border cases. It also hosts the UK's international liaison capability.
PSNI's specialist unit. Its public-facing 'Cyber Protect/Prevent' function focuses on prevention, awareness and supporting SMEs, charities and individuals; investigation of cyber-enabled crimes (online harassment, stalking, threats) is carried out through PSNI's normal crime-investigation route after you report via 101 / 999 / the online portal. Treat it as the in-force specialist resource behind a PSNI report, not a separate public intake.
