Tom Ahern, a spokesperson for the Chicago Police Department, reported on multiple incidents in Chicago through his Twitter account on November 18, 2025. The tweets provided information about an armed robbery and a police-involved shooting.

At 16:44 UTC, Ahern posted: "ARMED ROBBERY with a FIREARM on #CTA @ChicagoCAPS07 @Area1Detectives Public Transportation Detectives https://t.co/Fq9ZojkxEa #ChicagoPolice https://t.co/gMa9lhTfbX". The message referenced an armed robbery involving a firearm that occurred on the Chicago Transit Authority system.

Later that day at 19:37 UTC, Ahern addressed media logistics regarding another incident: "Media staging for the police-involved shooting in @ChicagoCAPS02 @Area1Detectives Investigative Response Team is the southeast corner of 55th/Michigan. Additional information to follow. #ChicagoPolice". This tweet indicated ongoing police activity and preparations for press coverage near the intersection of 55th Street and Michigan Avenue.

A final update came at 21:41 UTC when Ahern issued a preliminary statement about the same event: "Preliminary Statement of Police-Involved Shooting in the 5600 block of S. Michigan Ave. @ChicagoCAPS02 @Area1Detectives Investigative Response Team #ChicagoPolice https://t.co/ZlHib7fOje".

The events described by Ahern reflect routine communication efforts by law enforcement agencies to inform both the public and media about ongoing investigations and critical incidents in urban areas such as Chicago. Public updates like these are standard practice for major city police departments to maintain transparency during active investigations or after significant criminal incidents.
