The Investigations Division is responsible for all investigative case follow-up. Detectives assigned to the division are involved in all areas of criminal investigations, including crimes against persons and/or property, financial crimes, financial identity theft, juvenile offenses, and cyber crimes.

Each detective has received specialized training in criminal law, major case investigations, forensic evidence interpretation, death investigations, sexual assault, and juvenile offenses. In addition, they participate in the DuPage Metropolitan Emergency Response and Investigations Team (MERIT), which is a multi-jurisdictional task force involving major crime investigations.

Alcohol & Tobacco Compliance Checks

The goal of compliance checks is to reduce the opportunity for underage individuals to acquire alcohol or tobacco products. The Problem Oriented Policing Unit (POP) conducts these compliance checks at city liquor and tobacco retailers and establishments. Results of the compliance checks are sent to the management of each establishment and to the mayor, in his capacity as the City Liquor Commissioner.

Confidential Tip Line - 630-393-5757
Using the confidential tip line, persons may leave an anonymous tip about criminal activity without having to leave personal information. When a tip is received, Detectives will investigate the information and follow up. By using the confidential tip line, persons who may otherwise not become involved (or fear becoming involved) may leave important information for police to investigate.

B.A.S.S.E.T Training Program

The Illinois Liquor Control Commission (ILCC) is the regulating agency for the Beverage Alcohol Sellers and Servers Education and Training (BASSET) program. The main focus of the BASSET program is to make sellers and servers of alcoholic beverages aware of Illinois law pertaining to sales and service of alcoholic beverages, DUI and Dram Shop laws, victims’ rights, and how to properly check ID’s.  BASSET training is not mandatory in Illinois, but the ILCC does encourage voluntary participation to promote responsible alcohol service and prevent alcohol-related fatalities. To schedule training, or if you have questions, please contact Sergeant Wittenberg at 630-393-2131.

Investigations Division Specialized Units

Juvenile Officer

The Police Department currently has two designated officers.

Problem Oriented Policing (POP UNIT)

The Problem Oriented Policing Unit (POP) specializes in crime suppression. The officers selected for this assignment are highly trained in drug enforcement, gang and vice investigations, and issues affecting quality of life. POP Unit officers identify and aggressively enforce laws and ordinances in order to reduce crimes of opportunity, and enhance the safety and security of the community.

POP Unit officers also employ strategies to identify at-risk youth, and provide diversionary measures in an attempt to correct youth offender behavior. These assigned officers spend considerable amounts of time problem-solving, and are not restricted to a geographical patrol zone.
