Captain's Message

 Thank you for visiting the St. Louis County Police Department Affton Southwest Precinct’s web page. The men and women of the St. Louis County Police Department are committed to providing the best police services available to residents and businesses in the communities we serve. I am pleased to tell you that overall crime is down 1.4% in the 3rd quarter compared to last year in the Affton Southwest Precinct. We are seeing thefts from vehicles as the leading crime trend over the past several months in the precinct. Please remember to remove all valuables from your vehicles when unattended. These suspects are targeting vehicles that have items left in them. Items they are looking for include electronics, purses, phone chargers, weapons and change to name a few.

 With Halloween quickly approaching I would like to remind drivers to be extra careful and cognizant of the young children that will be trick-or-treating. These young children get distracted by the excitement of the night and aren’t paying attention to their surroundings. These children run across the street without looking and are usually wearing dark colored costumes making them difficult to see. Please slow down while driving in residential areas.

 Please continue to contact the police when you see anything suspicious. With your help we can continue to make the Affton Southwest Precinct a safe and enjoyable place to live and work.

Report Crime ... Make the Call

If you see a crime in progress or another emergency situation that requires an immediate police response, call 911. Provide the call-taker with a good description of the incident, the offender, and the exact location.

For non-emergencies, however, do not call 911. Non-emergency calls to 911 can slow the response time to true emergencies. The number to call for non-emergencies is (314) 889-2341.
