The Special Operations Bureau contains a number of specialty functions to address community needs and support the many functions of a police agency. The Special Operations Bureau is commanded by a Deputy Chief and two Lieutenants with responsibility for the following squads.

  • Accident Investigations

    The Accident Investigation/Hit & Run Unit is comprised of officers that are trained in accident investigations and reconstruction. These officers respond to major traffic accidents in Salt Lake City and handle the investigation from start to finish. The officers assigned to this unit undergo hundreds of hours of extensive training for accident investigation, accident reconstruction and court testimony.

    The unit has the primary role of traffic accident investigation and enforcement in Salt Lake City. The teams goal is to reduce the number of traffic accidents in the City and assist our partner agencies in the design of our roadways and traffic control devices.

    The unit also teams with the Motorcycle Squad during events such as the Days of ’47 Parade, the Gay Pride Parade and many other functions, including LDS General Conference, dignitary escorts, and protests and mass gatherings.

  • HDU - Hazardous Devices Unit

    The Salt Lake City Police Department Hazardous Devices Unit, aka Bomb Squad, includes five FBI-certified bomb technicians, supported by two bomb technicians from the Salt Lake International Airport Police Department and one bomb technician from the University of Utah Police Department. The Bomb Squad is accredited by the FBI and is a member of Utah’s statewide Bomb Response Task Force. Members of the squad range in experience from one to 11 years with training in render safe procedures, explosive destruction, blast mitigation, and post blast investigation.

    The bomb squad has full bomb and explosive recovery response capabilities, utilizing all the latest equipment and technology.




  • K9

    The Salt Lake City Police Department K9 Unit was established in 1958 and, although the unit was dissolved for a short period, the squad continues to be an enormous support function for Salt Lake City and the employees of the police department.

    The police department has seven K9 teams made up of an officer teamed with a police service dog, either a German shepherd or a Bloodhound.  The shepherd teams are best known for their abilities in apprehending criminals who attack or flee from officers and their ability to sniff drugs. The Bloodhounds are best known for their ability to track suspects and lost children.

    K9 Squad FAQ

    Where do the Police Service Dogs live?
    Once selected, a new police service dog is assigned to a K9 officer. Not only does the dog become an important member of our “police family,” but it also becomes a very important member of the officer’s family. When not at work our dogs spend time with their families but they always have access to a quiet area where they can get plenty of rest.

    Do the K9 Teams visit schools and other social gatherings?
    Yes, they do visit schools and other community gatherings. They are not available for birthday parties or other private functions. Please call (801) 799-3400 to arrange a visit.

    Can I support the SLCPD K9 Unit?
    Yes. The K9 Unit operates on a very tight budget. Our dogs are fed high-quality food and they receive the best veterinary care. Our budgetary limitations, however, make it difficult for us to attend training events and K9 competitions. Our officers feel strongly that by keeping their police service dogs on the cutting edge of proficiency, they are keeping them, other officers and the public safe. If you would like to invest in the safety of our dogs and in the effectiveness of their work, donations can be made to:

    Can I touch/pet the police service dogs?
    Like any police service dog, you must ask the handler if you can touch the K9 before you do. Police service dogs are trained to protect themselves and their handlers, so it is important that the handler introduce you to his or her dog properly.

    Do the K9s like to bite?
    The K9s only bite when absolutely necessary to protect themselves, their handlers, another officer, a citizen or when they need to capture a fleeing felony suspect. Most often, when faced with a confrontation with a police dog, criminal suspects choose to surrender. When our dogs do bite, they are trained to grip and hold the suspect until their handler is able to take over. This results in very minor injury to the suspect. Salt Lake Police K9s are primarily used as search tools. They enjoy hunting for and finding people, articles of evidence and illegal drugs.

    What kind of dogs do you use?
    We have 2 German Shepherds and 2 Belgian Malinois both are dual-purpose patrol/drug detection dogs. We have 3 Bloodhounds that specializes in tracking, and one Labrador that specializes in drug detection that is assigned to the DEA.

    Who trains the dogs?
    We train all of our dogs in-house. Officer Cale Lennberg is our head patrol/drug dog instructor. Our dogs are certified by the state of Utah and must pass a proficiency examination annually. Officer Mike Serio is our head bloodhound instructor.

    How old are the dogs when they start training?
    We normally purchase police dog candidates that are between 18 months and 2½ years old. Dogs can begin their training at a very young age. Our bloodhounds were purchased as puppies. Their training began when they were about 2 months old!

    How long are the dogs trained?
    Basic training for our dual-purpose patrol and drug detection dogs takes four months of full-time work. Additionally, our dogs receive 2 hours of in-service training during each of their 10 hour shifts.

    How old are the dogs when they retire?
    Our rule of thumb for retiring police dogs is 7 years of service or 10 years of age. Of course, actual retirement depends on the physical condition of the dog. Going to work every week is the most important thing in the world to each of our dogs. Early retirements are not fair to them unless there is a physical limitation.

    Where do they go when they retire?
    Our dogs are members of the officer’s family and they retire with that family in every case. If a service dog has worked with more than one officer during its career, the dog normally retires with the last officer that it worked with.

    How do officers get selected to become K9 handlers?
    K9 officer candidates must pass a rigorous screening process. Several officers compete for each position. We choose our K9 officers from among the most effective officers in the department. Each candidate is then evaluated on many dimensions in order to determine which will be the most effective when paired with a police service dog.

    Where does the Salt Lake Police Department get its dogs?
    Police dog candidates must possess certain drives, instincts and character traits in order to be considered. Very few dogs pass our screening process. We sometimes import dogs from Europe due to the small numbers of qualified candidates in the United States.

    How much do the dogs cost?
    The dogs that meet our high standards cost from $5,000–$7,000. Fortunately, when measured in terms of effectiveness and community safety, the payback period on the initial investment is very short!

    How is a dog able to smell so well?
    A number of things contribute to a dog’s keen sense of smell. Their long snouts have a large turbinate bone structure that holds millions of scent receptor cells, plus the olfactory lobe of their brain is much larger than that of a human being.

    Is hurting a police service dog the same as hurting a police officer?
    Injuring or killing a police service dog is a 3rd degree felony punishable by imprisonment of up to 5 years. We invest considerable resources in our K9 partners and we consider them officers in every sense. They put their lives on the line every day to protect the community and the officers of the Salt Lake City Police Department.

  • Motorcycle Squad

    Motors consists of many well-trained motorcycle riders who are responsible for traffic enforcement throughout the City.  The motorcycle squad utilizes BMW and Harley-Davidson motorcycles, which enable the officers to move freely through congested traffic and more effectively accomplish their mission.

    The squad trains on a regular basis so the officers can maintain their skills and their safety while working in highly-congested areas as well as all of the special functions they work throughout the year.

    The unit deploys City-wide to address major traffic concerns, and it responds to citizen complaints in neighborhoods.  Motors officers educate the public about safe driving while enforcing the laws.

    The squad works many special events during the year, including parades, funerals, sporting events, runs, and more.  The squad is mostly known for its precision riding during the 24th of July parade, which is attended by thousands of community members.

  • School Resource Officers

    The School Resource Officers Unit is comprised of eight officers and a sergeant.  The SROs are currently assigned on campus at East High, West High, Highland High, Horizonte, Glendale Middle School, and Northwest Middle School, with collateral assignments at three middle schools and 28 elementary schools in the Salt Lake City School District.

    The School Resource officer has a diverse role within the schools and communities and has many duties and responsibilities. As a sworn officer assigned to a school on a long-term basis trained to perform various roles to include law enforcement officer, law related counselor, law related educator addition, in the officer works in collaboration with the school and the community as a resource for safety and security issues.

    As an officer for SLCPD, the school becomes the officer’s beat. The SRO assists the school administration in maintaining a safe and secure environment. School administrators benefit from the SROs training, knowledge and experience is handling situations involving possible violations of the law. The SRO provides a highly visible presence to deter or identify trespassers on campus, in addition the SRO’s provide a service to the surrounding community by addressing concerns involving students such as truancy, loitering and criminal mischief which, when going to or from school often generate these types of community complaints.

    The School Resource Officer has a defined role that is separate from that of the School administration as set forth by an agreement and MOU of the DMC (Disproportionate Minority Contact) committee. School Resource Officers will work with the DMC committee and school administration to find diversionary programs in dealing with status offenses and find alternative solutions to dealing with problems in the schools.

    The School Resource officer should be a positive role model, it is essential for an SRO to endorse high moral standards and use good judgment and discretion when dealing with students to help them learn and understand what a professional police officer does.

    It is important to note that School Resource Officers are responsible for investigating violations of law, and when appropriate, make arrests. They are not school disciplinarians and are not involved in investigating school rule violations or district policies.
