2. The question required to be decided is `whether the detention period of the petitioner from 2nd July 2003 to 6th September 2004 in United State of America would amount to his “period of detention” as understood by section 428 of Code of Criminal Procedure, 1973 (Cr.P.C.)?’ The facts are admitted and can be stated as under:

3. Offence under section 377 etc. was registered by Colaba Police Station on 15th November 2001 vide Crime No.312/2001. The name of the petitioner was shown as one of the accused since beginning. The police, therefore, went in search of the petitioner. After investigation, it was learnt that the petitioner had gone out of India and would be found in America etc. Accordingly, the police obtained warrant of arrest from the concerned Magistrate. It was a red corner notice issued to Central Bureau of Investigation (C.B.I.). Pursuant to this notice/ warrant, the petitioner was arrested in America on 2nd July 2003 at New York. He was admittedly not wanted in any other case in America at that time. He was admittedly arrested pursuant to the warrant issued by the Indian Court. Investigation Officer then started procedure for extradition of the petitioner from America to India and pursuant to certain extradition treaty, the competent Court in America allowed extradition of the petitioner to India. This order was passed on 24th November 2003 and on 6th September 2004 the petitioner was finally brought to India. It is, thus, an admitted fact that the petitioner was under the detention of the America Court from 2nd July 2003 to 6th September 2004. The Sessions Court vide order dated 18th March 2006 convicted the petitioner for various offences and sentenced him to suffer rigorous imprisonment. After the petitioner was convicted, the usual order of set off was passed. The said order was not disturbed by the final Court. The question is whether the detention period of the petitioner in America is a period of detention as understood by section 428 of Cr.P.C. Section 428 of Cr.P.C. reads as under:

“428. Period of detention undergone by the accused to be set off against the sentence of imprisonment. - Where an accused person ha, on conviction, been sentenced to imprisonment for a term, not being imprisonment in default of payment of fine, the period of detention, if any, undergone by him during the investigation, inquiry or trial of the same case and before the date of such conviction, shall be set off against the term of imprisonment imposed on him on such conviction, and the liability of such person to undergo imprisonment on such conviction shall be restricted to the remainder, if any, of the term of imprisonment imposed on him:”

4. It is said that the petitioner was arrested in America during investigation of this crime. The question is what is investigation and the answer would be found in the definition of term `investigation’ given in section 2(h) of Cr.P.C., which reads as under:

“2. Definitions. – In this Code, unless the context otherwise requires, -

(a) to (g) ..... ..... ..... ..... .....

(h) “investigation” includes all the proceedings under this Code for the collection of evidence conducted by a police officer or by any person (other than a Magistrate) who is authorised by in this behalf;

5. Thus, all the proceedings permissible under Cr.P.C., for collection of evidence, is investigation. The moment offence was registered in this case, the investigation started. The police at one hand arrested other accused in this case and also recorded the statement of various witnesses while the petitioner was abroad and eluding his arrest. The investigation was going on. When the police sought arrest warrant against the petitioner, the same was part of investigation and such warrant was issued under the provisions of section 166 read with section 70 of Cr.P.C. The proceedings adopted by the Investigation Officer for seeking arrest warrant against the petitioner
