You are in England & Wales and the person doing this is in South Africa. You report at home, and at the same time trigger action where they actually are.
999 (call and ask for the police if you or someone else is in immediate danger or a crime is in progress). 112 also connects to the same emergency operator across the EU/UK.
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 England & Wales. At the same time, the fastest leverage often sits in South Africa, where the person actually is.
The fastest live protection/unmasking lever against a locally-located perpetrator is the Protection from Harassment Act. A South African magistrate's court can, under s.4, direct a South African electronic communications service provider to FURNISH the unknown harasser's name, identity number and address - identifying an SA-based harasser without any extradition - and then issue an interim and final protection order (s.10), breach of which is a crime (up to 5 years, s.18(1)(a)). This means a victim does NOT need extradition to get relief: the SA courts act directly against SA-based persons and SA-licensed service providers. IMPORTANT CORRECTION: the Cybercrimes Act s.20 takedown order and s.21 unmasking direction are NOT yet in operation (Part VI of Chapter 2 has not been commenced as of 2026), so there is currently no operative Cybercrimes Act statutory takedown order; content removal goes through the protection-order conditions plus direct reporting to the platform/host. A foreign victim typically needs a local contact (e.g. SA-based counsel, or coordination via SAPS once a docket exists) to drive the magistrate's-court application, since these orders are made by SA courts against SA-licensed providers.
When the perpetrator is located in South Africa and the victim is abroad, the inbound police-to-police route runs through INTERPOL NCB Pretoria. A foreign victim reports to their OWN national police, who route a request through their INTERPOL National Central Bureau to NCB Pretoria (which sits inside SAPS Crime Intelligence). NCB Pretoria is the channel for international investigations requiring SAPS cooperation and triggers SAPS action against a South Africa-based suspect. For formal evidence-gathering and execution, requests run as Mutual Legal Assistance under the International Cooperation in Criminal Matters Act 75 of 1996, with the South African Department of Justice & Constitutional Development as the Central Authority; dual criminality is not a strict requirement for incoming requests. NOTE: the Cybercrimes Act's 's.52 designated point of contact' and the Chapter 5 mutual-assistance provisions (ss.46-52) are enacted but NOT yet in force as of 2026, so they cannot currently be relied on - use INTERPOL NCB Pretoria and the 1996 MLA Act.
For US-nexus matters the FBI maintains a Legal Attache (Legat) office at the U.S. Embassy in Pretoria; confirm current contact details with the U.S. Embassy Pretoria.
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.
Use the online report form for non-emergency stalking, harassment, threats, defamatory/abusive content. For stalking/harassment many forces use a dedicated 'Report online' button that triages you to the right form. CRITICAL for a paper trail: at the end of the report ASK FOR and record the crime reference number / occurrence / log number; the report is handled by the control room the same as if you spoke to an officer. Keep screenshots and evidence.
Call 101 to report a non-emergency crime or get advice and to generate an official log. Ask for a crime/incident reference number. Also the route for Scotland fraud reporting (Police Scotland).
Anonymous reporting if you do not want to give your details. NOTE: This does NOT create a victim crime report or give YOU a personal crime reference number, so it is not the channel for starting your own official paper trail; use 101 or local-force online report for that.
Use for fraud, online extortion/sextortion demanding money, identity fraud/identity theft, and cyber-dependent crime. Generates a reference number for your paper trail. Covers England, Wales and Northern Ireland; Scotland callers report to Police Scotland on 101. Report Fraud went live 4 December 2025 with Action Fraud traffic redirecting and a full public launch in January 2026.
File here in addition to, not instead of, your local police report.
INTAKE + TRIAGE + INTELLIGENCE, generally NOT a direct investigator of individual reports. National reporting front door for fraud and cyber-crime (replaced Action Fraud; full public launch January 2026, redirects began 4 Dec 2025). Reports are assessed by the Report Fraud National Crime Analysis Service (N-CAS) and disseminated to local forces or specialist units; serious/complex cases are flagged for investigation. A victim support service is provided. Phone unchanged from Action Fraud (0300 123 2040).
Investigates the most serious and organised cyber-crime; leads, supports and coordinates the UK response to serious/organised crime including cybercrime and economic crime that crosses borders. The public does NOT report routine cybercrime directly to the NCA - the NCA directs victims to local police (101/999) or Report Fraud; it acts on intelligence and serious-organised-crime cases, not individual intake.
INTAKE + TECHNICAL TAKEDOWN, not a criminal investigator of harassment. Receives reports of scam/phishing emails, texts and websites; can investigate and remove malicious sites and shares intelligence with the NCA and City of London Police. Not the channel for harassment/threats/doxxing - it is for scam/phishing infrastructure.
PLATFORM REGULATOR, NOT an individual-complaint body and does NOT investigate your specific case or give you a personal remedy. Regulates social-media and search platforms' duties to remove illegal content (including harassment, threats, intimate-image abuse). Can fine platforms up to 10% of qualifying worldwide revenue (or 18 million pounds, whichever is greater) and, in extreme cases, seek court orders to block a service. Victims still report the crime to police; Ofcom handles systemic platform compliance. Illegal-content duties live since 17 March 2025.
