The Investigative Services Division, which is made up of general detectives, is responsible for the majority of follow up investigations (which includes homicide, assaults, robbery, theft, burglary, financial crimes and juvenile crimes). The Special Investigations Unit, which focuses on gang, drug and vice offenses, is a specialized group of detectives who monitor graffiti, gang movement and track drug activity. The Problem Oriented Policing Unit, also referred to as the POP Unit, works with community members to resolve ongoing neighborhood issues. The POP Unit also works with Crime Prevention to put Neighborhood Watch programs in place.
