criminal trial – Arrest – bail – Special Judge was labouring under a misconception that in every non-bailable and cognizable offence the police is required to invariably arrest a person, even if it is not essential for the purpose of investigation. . Rather the law is otherwise. In normal and ordinary course the police should always avoid arresting a person and sending him to jail, if it is possible for the police to complete the investigation without his arrest and if every kind of co-operation is provided by the accused to the Investigating Officer in completing the investigation. It is only in cases of utmost necessity, where the investigation cannot be completed without arresting the person, for instance, a person may be required for recovery of incriminating articles or weapon of offence or for eliciting some information or clue as to his accomplices or any circumstantial evidence, that his arrest may be necessary. Such an arrest may also be necessary if the concerned Investigating Officer or Officer-in-charge of the Police Station thinks that presence of accused will be difficult to procure because of grave and serious nature of crime as the possibility of his absconding or disobeying the process or fleeing from justice cannot be ruled out.
