Ordinarily, arrest is a part of the process of investigation intended to secure several purposes. The accused may have to be questioned in detail regarding various facets of motive, preparation, commission and aftermath of the crime and the connection of other persons, if any, in the crime. There may be circumstances in which the accused may provide information leading to discovery of material facts. It may be necessary to curtail his freedom in order to enable the investigation to proceed without hindrance and to protect witnesses and persons connected with the victim of the crime, to prevent his disappearance to maintain law and order in the locality. For these or other reasons, arrest may become inevitable part of the process of investigation. The legality of the proposed arrest cannot be gone into in an application under Section 438 of the Code. The role of the investigator is well-defined and the jurisdictional scope of interference by the Court in the process of investigation is limited. The Court ordinarily will not interfere with the investigation of a crime or with the arrest of accused in a cognizable offence. An interim order restraining arrest, if passed while dealing with an application under Section 438 of the Code will amount to interference in the investigation, which cannot, at any rate, be done under Section 438 of the Code. The above position was highlighted in Adri Dharan Das v. State of West Bengal (2005) 4 SCC 303).[Parvinderjit Singh and Another Versus State (U. T. Chandigarh) and Another AIR 2009 SC 502 ]
