Code of Criminal Procedure, 1973 · Chapter XII: Information to the Police and Their Powers to Investigate
Section 166A: Letter of request to competent authority for investigation in a country or place outside India
The Code of Criminal Procedure, 1973 was repealed and replaced by the Bharatiya Nagarik Suraksha Sanhita, 2023 from 1 July 2024. It still applies to offences and proceedings from before that date.
In plain words
If an investigating officer applies saying evidence may be available abroad, any criminal court can send a letter of request to a competent court or authority in that country to examine witnesses and obtain documents or things, transmitted as the Central Government specifies. What is received counts as evidence collected in the investigation.
