Section 187 in The Code of Criminal Procedure
Title: Power to issue summons or warrant for offence committed beyond local jurisdiction
(1) When a Magistrate of the first class sees reason to believe that any person within his local jurisdiction has committed outside such jurisdiction (whether within or outside India) an offence which cannot, under the provisions of sections 177 to 185 (both inclusive), or any other law for the time being in force, be inquired into or tried within such jurisdiction but is under some law for the time being in force triable in India, such Magistrate may inquire into the offence as if it had been committed within such local jurisdiction and compel such person in the manner hereinbefore provided to appear before him, and send such person to the Magistrate having jurisdiction to inquire into or try such offence, or, if such offence is not punishable with death or imprisonment for life and such person is ready and willing to give bail to the satisfaction of the Magistrate acting under this section, take a bond with or without sureties for his appearance before the Magistrate having such jurisdiction.
(2) When there are more Magistrates than one having such jurisdiction and the Magistrate acting under this section cannot satisfy himself as to the Magistrate to or before whom such person should be sent or bound to appear, the case shall be reported for the orders of the High Court.
Title: Offence committed outside India
When an offence is committed outside India--
(a) by a citizen of India, whether on the high seas or elsewhere; or
(b) by a person, not being such citizen, on any ship or aircraft registered in India,
he may be dealt with in respect of such offence as if it had been committed at any place within India at which he may be found:
Provided that, notwithstanding anything in any of the preceding sections of this Chapter, no such offence shall be inquired into or tried in India except with the previous sanction of the Central Government.
Title: Receipt of evidence relating to offences committed outside India
When any offence alleged to have been committed in a territory outside India is being inquired into or tried under the provisions of section 188, the Central Government may, if it thinks fit, direct that copies of depositions made or exhibits produced before a Judicial officer in or for that territory or before a diplomatic or consular representative of India in or for that territory shall be received as evidence by the Court holding such inquiry or trial in any case in which such Court might issue a commission for taking evidence as to the matters to which such depositions or exhibits relate.
Title: Cognizance of offences by Magistrates
(1) Subject to the provisions of this Chapter, any Magistrate of the first class, and any Magistrate of the second class specially empowered in this behalf under sub-section (2), may take cognizance of any offence--
(a) upon receiving a complaint of facts which constitute such offence;
(b) upon a police report of such facts;
(c) upon information received from any person other than a police officer, or upon his own knowledge, that such offence has been committed.
(2) The Chief Judicial Magistrate may empower any Magistrate of the second class to take cognizance under sub-section (1) of such offences as are within his competence to inquire into or try.
Title: Transfer on application of the accused
When a Magistrate takes cognizance of an offence under clause (c) of sub-section (1) of section 190, the accused shall, before any evidence is taken, be informed that he is entitled to have the case inquired into or tried by another Magistrate, and if the accused or any of the accused, if there be more than one, objects to further proceedings before the Magistrate taking cognizance, the case shall be transferred to such other Magistrate as may be specified by the Chief Judicial Magistrate in this behalf.
