Specialized Units

Bike Patrol

The Bike Patrol Unit was re-launched after nearly a decade of absence. In mid-2013, officers began to patrol certain areas and events within the City with the goal of increasing visibility and improving connections with citizens. To be certified as a bike patrol officer, candidates must go through an extensive 48-hour training course, in which they learn bicycle rules of the road, arrest tactics from a bicycle, tips for night riding, slow riding for working in crowds, and physical training to jump from a bike to handle any type of confrontation. Officers in this Unit are outfitted with special uniforms and equipment to allow for more freedom of movement and officer visibility. While patrolling the community, officer emphasis is geared toward parks and bike paths.

Forensic Evidence Unit

This unit consists of highly trained police officers who are able to identify and recover forensic evidence at crime scenes. The Police Department is trained and equipped to process crime scenes that involve incidents from vandalism to homicides. This capability gives Warrenville police officers opportunities to link suspects to crimes through nearly forensic evidence, such as fingerprints and DNA. Additionally, by processing every viable crime scene, the unit officers can collect and compare forensic evidence to other reported crimes.

Most often, a criminal offender leaves or takes physical evidence with them from a crime scene. By having the right equipment and training, police officers can seek to identify and collect this evidence.

The members of this unit participate in the DuPage Metropolitan Emergency Response and Investigation Team (MERIT) during major crimes call outs. The opportunity to work with DuPage County’s best and most skilled forensic evidence technicians allows Warrenville officers develop their skills and knowledge base.

K-9 Unit (Retired)
Police canines are specially trained German Shepherds who can detect drugs, and assist in searches for people, articles, and criminal suspects. Canine handlers and their canine counterparts jointly and extensively train to meet State of Illinois requirements. The Unit’s main focus is to patrol within the City; however, they may also assist other agencies with special call-outs and attend City events for K-9 duty demonstrations.

The City of Warrenville Police Department has had two police canines. The Police Department’s first canine was K-9 Bandit who joined the force in 2002. K-9 Bandit served the City for over eight years, until his retirement in 2010.

The most recent canine, K-9 Baron, joined the force in 2010. In December of 2012, K-9 Baron received a Kevlar-for-K9 ballistic safety vest donation. This donation was made possible through a company that looks at police communities where ballistic vests have not been appropriated for their canine-counterparts. K-9 Baron served the City until his retirement in December of 2014.

The Police Department currently does not have an active K-9 Unit.

Traffic Safety Enforcement Unit

Established in 2013, the Unit is comprised of two officers working two shifts, covering six days per week during peak call for service and heaviest traffic times. The Unit focuses on traffic law enforcement, overweight truck enforcement, accident investigation, and is fiscally self-sustaining.

Truck Enforcement

The Truck Enforcement Unit’s focus is on overweight trucks and truck safety. Special permits are required for city streets for overweight/over height vehicles. Oxcart Permitting Systems is used to apply for these permits. The links to the City Code regarding overweight/over height vehicles and to the permit application are available on this website.
