Difference between Investigation and Inquiry: Investigation involves a systematic process of examining and gathering evidence to uncover facts or resolve a specific matter, often pertaining to legal or serious issues. On the other hand, inquiry refers to a less formal exploration or seeking of information to gain understanding or knowledge about a subject.
.Section 169 of the CrPC reads as under:
“169. Release of accused when evidence deficient.—
If, upon an investigation under this Chapter, it appears to the
officer in charge of the police station that there is not sufficient
evidence or reasonable ground of suspicion to justify the
forwarding of the accused to a Magistrate, such officer shall, if
such person is in custody, release him on his executing a bond,
with or without sureties, as such officer may direct, to appear, if
and when so required, before a Magistrate empowered to take
cognizance of the offence on a police report, and to try the
accused or commit him for trial.”
Reinvestigation defined:
the act or process of carefully examining a crime, problem, statement, etc. again, especially to discover the truth. Understanding the Concept of Further Investigation
As a result, if a charge-sheet has been filed, the investigating agency may conduct additional investigations, and the Court may order more investigations. However, any further investigation will not imply a new investigation or a reinvestigation.
