City of Highland Park Police Respond to Barricade Incident

City of Highland Park Police Respond to Barricade Incident

May 1, 2024 – On Tuesday, April 30, 2024, at approximately 10:43 PM, the City of Highland Park Police Department responded to a domestic battery call in the 1500 block of McDaniels Avenue in Highland Park. Upon arrival on scene, officers discovered multiple individuals in the home, who were safely evacuated by police. The suspect was identified as Diego Rosas, 22 years of age.

Responding officers determined that the suspect was barricaded inside a room in the home and reportedly armed with a machete. Officers established a safety perimeter and began attempting to  negotiate with the suspect.

After some time and with no response from the suspect, Highland Park Police requested additional support from the Northern Illinois Police Alarm System (NIPAS) Emergency Services Team (EST). NIPAS fortified the safety perimeter while negotiators continued to attempt to make contact with the suspect. EST peacefully resolved the incident by taking the suspect into custody at approximately 2:45 AM on Wednesday, May 1. The City appreciates the partnership of NIPAS in providing critical mutual aid from neighboring law enforcement agencies.

After reviewing the evidence and facts of the investigation with the Lake County State’s Attorney’s Office, Rosas was charged with two counts of Domestic Battery. Rosas has been transported to the Lake County Courthouse for a first appearance hearing on May 1, 2024.

As the incident occurred overnight, the City will be reaching out directly to residents in the immediate vicinity who previously provided their contact information via phone call, email, and text message (as available) to provide information about this incident. Through its Smart 911 service, the City is able to issue communication to residents in a designated geographic area, as in this case, as well as emergency alerts to the community as a whole. All Highland Park residents are encouraged to sign up for Smart 911 at, which also provides critical information to first responders about household members in the event of an emergency.

The City is also preparing to launch an opt-in text messaging service for one-way public safety alerts; community members interested in receiving these alerts may text HPAlerts to 226787 to subscribe. Please note that this service does not affiliate phone numbers with residents’ names or locations.
