The Investigative Services Division is commanded by a Captain and is the primary investigative component of the Norwalk Department of Police Service. The division is comprised of the Detective Bureau, Youth Bureau and Special Services Unit.

Detective Bureau
The Detective Bureau is under the command of a Lieutenant. The organizational structure of the Bureau includes three squads of detectives, each supervised by a Sergeant, assuring coverage from 8am until midnight, seven days a week.

The Bureau is required to assume responsibility for all felonies where a follow-up investigation is required and necessary, any misdemeanors where a follow-up investigation is deemed necessary by the detective supervisor, and any other matter determined by the Chief of Police to be appropriate.
Most Part I category crimes (Murder, Robbery, Sexual Assault, Burglary, Arson, Larceny and Stolen Motor Vehicles) are investigated by the detectives in this unit.

Realizing cooperation and coordination among various law enforcement agencies is essential to reducing the level of crime and solving crimes where they do occur, the Detective Bureau cooperates with other city, state and federal agencies in investigating incidents utilizing task forces or other cooperative means.

To attain the rank of Detective, a Norwalk Police Officer must have a minimum of 3 years "on the job", and pass a competitive written and oral examination.

Youth Bureau
The Youth Bureau handles the investigation of crimes involving juveniles and cases of suspected child abuse. In addition, the Bureau provides instruction to all Norwalk 5th graders through the DARE (Drug Abuse Resistance Education)Program, to middle school students through GREAT (Gang Resistance Education ad Training) Program, and high school age students through POSITIVE (Police Officers And Students Involved Together In Valuable Education) Program.
These education programs are intended to improve the relationship between the Norwalk youth ad the police through a frank and open discussion of contemporary issues impacting our youth.

Special Services Unit
The Special Services Unit, commanded by a lieutenant, is responsible for the investigation of narcotics violations, vice, gambling and organized crime. As in most large cities, narcotics enforcement is the priority for this unit. Long term as well as short term investigation are conducted by this unit. Targets range from high-level narcotics traffickers to sellers and buyers engaged in street-level narcotics activities. Utilizing state and federal asset forfeiture laws, thousands in cash and property is seized each year, and used to further combat the drug problem. In addition, the unit works closely with federal agencies such as the FBI, Treasury Department and Drug Enforcement Administration, as well as state and regional units such as the State-Wide Narcotics Task Force.
