The Covert Response Unit (CRU) is the undercover enforcement branch of the Bureau of Investigations (BOI). The CRU is responsible for the apprehension of serious and violent felons through the use of covert surveillance techniques and tactics. The Unit investigates mid to high-level narcotics traffickers and distributors and conducts covert investigations related to other non-narcotic related offenses.

The CRU will assist the Federal Drug Enforcement Agency (DEA) and the Department of Justice Bureau Narcotics Enforcement (BNE) as needed relating to drug trafficking investigations. The CRU is also responsible for the enforcement of vice-related activity such as prostitution, massage parlors, gambling, bookmaking, extortion, and ABC violations.
