The Investigator’s Handbook: Bangladesh Edition

What the Bangladesh edition covers

1. Bangladesh 1. Domestic legal process: who can ask for what, and how

   This chapter sets out the Bangladeshi instruments an investigator uses to obtain data, money records and electronic evidence from providers inside Bangladesh: the Cyber Protection Act, 2026, the Code of Criminal Procedure, 1898, the Telecommunication Regulation Act, 2001 as amended in 2026, and the Money Laundering Prevention Act, 2012. Bangladesh’s cyber law changed several times between 2023 and 2026, so the chapter begins by saying which text is in force on 18 October 2026 and what each change did. It also says plainly who cannot use these powers and what an electronic record needs before a court will accept it.

2. Bangladesh 2. Internet and telecom providers in Bangladesh

   This chapter shows how to identify the Bangladeshi provider behind an IP address, a domain or a mobile number, what the provider must keep and for how long, and how to use our ISP and telecom directory to address a request. It is written for investigators working in Bangladesh. Bangladeshi providers publish very little about how they handle law enforcement requests, and this chapter says so wherever that is the case.

   • From an IP address to a provider

   • From a mobile number to a provider

3. Bangladesh 3. Banks, wallets and national reporting: money and complaints

   This chapter explains how a fraud loss is reported in Bangladesh, what holds or freezes funds quickly, what the customer’s bank and mobile wallet provider must do under the published rules, and how a complaint climbs to Bangladesh Bank. It also gives the official figures we could verify and links to our bank and wallet pages. Bangladesh has several partial routes, not a single national fraud portal with a published freeze procedure, and the chapter says where we could not find a published rule.

   Sections in this chapter

   • Reporting: where a loss is reported
   • How funds are held and traced
   • Tracing a transfer: which payment rail was used
   • What the customer’s bank or wallet provider must do, and by when
   • Wallet providers and their official routes
   • The complaint ladder for the account holder
   • Our pages for victims and officers
   • Official figures
   • Worked example (generic)
   • Checklist

4. Bangladesh 4. Cross-border: treaties, platform routes and what this country’s authorities can send out

   This chapter gives the treaty and convention position for Bangladesh, the statute and rules that govern mutual legal assistance in and out, the police channels we could verify, how Bangladeshi requests reach the large US platforms, and what a foreign agency should send to reach a Bangladeshi provider or bank. Bangladesh is not a Party to the Budapest Convention, has not signed the UN Convention against Cybercrime, and has no mutual legal assistance treaty or CLOUD Act agreement with the United States, so formal requests run through the Mutual Legal Assistance in Criminal Matters Act, 2012 and platform policies.

   Sections in this chapter

   • Treaty and convention position
   • The central authority and the procedure
   • Police-to-police channels
   • How Bangladeshi requests reach US platforms
   • What a foreign agency should send to reach Bangladeshi providers or banks
   • Decision flow
   • Checklist

5. Bangladesh 5. Templates, contacts and quick reference

   This chapter gives the national agencies you will deal with, three ready-to-adapt templates written for Bangladeshi law (a preservation application and request, a records request with the production routes, and an emergency request), a one-page “who do I call first” table by case type, and a quick reference of the sections and deadlines used in Chapters 1 to 4. Placeholders are in [SQUARE BRACKETS].

   Sections in this chapter

   • National agencies
   • Template 1: Preservation application and request to a domestic provider
   • Template 2: Records request and production application
   • Template 3: Emergency request
   • Who do I call first?
