The Internal Affairs Bureau (IAB) acts as the guardian of the Metropolitan Police Department’s reputation, and is charged with the accountability, implementation, and maintenance of the Department’s anti-corruption programs. It is an office of unparalleled integrity that provides effective corruption control and behavior accountability through comprehensive proactive and reactive investigations, inspections, and adjudications of misconduct and corruption. The IAB also collects extensive statistical data for review, assessment, and trend analysis.

The OPC Liaison Unit coordinates the investigation of those citizens' complaints filed with the Office of Police Complaints. The Internal Affairs Division also investigates lethal and serious non-lethal uses of police force.
- Court Liaision Division, which coordinates MPDC members' participation in court proceeedings and other court-related activities.
- Diversity and EEO Compliance Unit, which administers the Department's equal employment opportunity program, including investigating and adjudicating EEO-related complaints.
