Police Internal Investigations
I. INTRODUCTION TO POLICE INTERNAL INVESTIGATIONS
Definition:
Police internal investigations involve the examination of misconduct, corruption, or criminal activity by serving police officers. These investigations ensure accountability, integrity, and public trust in law enforcement.

CrPC Section 197: Investigations against public servants, including police officers, require sanction for prosecution.
Model Conduct Rules for Police: Provide internal disciplinary mechanisms.

Types of Internal Investigations:
Disciplinary Investigations: Breach of service rules (minor misconduct)
Criminal Investigations: Alleged criminal acts (bribery, murder, corruption)
Administrative Inquiries: Performance-related issues or misuse of authority
Key Features:
Often initiated suo motu by senior officers or on complaints
May involve internal police committees or special investigation units
Courts supervise when allegations involve criminal offenses
