Addison Police Investigate Possible Swatting Call at Stone Elementary

Police said emergency activity was reported in the area of Lombard Road between Army Trail Road and Driscoll Lane. Roadways in the area were blocked during the response, and residents were asked to stay away while first responders continued their work.

An alert to residents was issued shortly after 1:00 PM CDT on Thursday, May 21, 2026. Police later updated the public, saying the investigation remained active and that authorities and school administrators were reviewing a potential swatting call involving Stone Elementary School.

Why Swatting Calls Trigger Major School Responses

Swatting refers to a false emergency report intended to draw a major law-enforcement response. The FBI has warned that swatting threats can create real public-safety risks and divert emergency resources from legitimate incidents.

Authorities did not immediately release further details about the source of the possible call, the nature of the report or when all nearby roads would fully reopen. The investigation remained focused on student and staff safety as police worked to determine what prompted the emergency response.
