63 STAT.] 81ST CONG., 1 ST SESS.-CH. 139-MAY 24, 1949 "§ 3653. Report of probation officer and arrest of probationer "When directed by the court, the probation officer shall report to the court, with a statement of the conduct of the probationer while on pro- bation. The court may thereupon discharge the probationer from further supervision and may terminate the proceedings against him, or may extend the probation, as shall seem advisable. "Whenever during the period of his probation, a probationer here- tofore or hereafter placed on probation, goes from the district in which he is being supervised to another district, jurisdiction over him may be transferred, in the discretion of the court, from the court for the district from which he goes to the court for the other district, with the concurrence of the latter court. Thereupon the court for the district to which jurisdiction is transferred shall have all power with respect to the probationer that was previously possessed by the court for the district from which the transfer is made, except that the period of probation shall not be changed without the consent of the sentencing court. This process under the same conditions may be repeated when- ever during the period of his probation the probationer goes from the district in which he is being supervised to another district. "At any time within the probation period, the probation officer may for cause arrest the probationer wherever found, without a warrant. At any time within the probation period, or within the maximum pro- bation period permitted by section 3651 of this title, the court for the district in which the probationer is being supervised or if he is no longer under supervision, the court for the district in which he was last under supervision, may issue a warrant for his arrest for violation of probation occurring during the probation period. Such warrant may be executed in any district by the probation officer or the United States marshal of the district in which the warrant was issued or of any district in which the probationer is found. If the probationer shall be arrested in any district other than that in which he was last supervised, he shall be returned to the district in which the warrant was issued, unless jurisdiction over him is transferred as above pro- vided to the district in which he is found, and in that case he shall be detained pending further proceedings in such district. "As speedily as possible after arrest the probationer shall be taken before the court for the district having jurisdiction over him. There- upon the court may revoke the probation and require him to serve the sentence imposed, or any lesser sentence, and, if imposition of sentence was suspended may impose any sentence which might origi- nally have been imposed.".

(c) The tenth paragraph of such section 3731 is amended to read as follows: "If an appeal shall be taken, pursuant to this section, to the Supreme Court of the United States which, in the opinion of that Court, should have been taken to a court of appeals, the Supreme Court shall remand the case to the court of appeals, which shall then have jurisdiction to 81939°-50---PT.
