Sterling Heights, Michigan – A 52-year-old man is in custody following a tense standoff after he barricaded himself inside the Stellantis Sterling Heights Assembly Plant on July 12, 2025. The situation began around 4 p.m. when police were alerted via a 911 call about an armed individual inside the facility, possibly experiencing a mental health crisis.

The assembly plant, located at 83111 Van Dyke Ave., was not operating at the time of the incident, with only a “skeleton crew” present. Authorities confirmed that all employees were evacuated safely before police established a perimeter around the site, isolating the suspect in a designated area of the plant.

During the three-hour ordeal, a crisis negotiation team collaborated with a special response team to communicate with the man and persuade him to surrender peacefully. Fortunately, the standoff concluded without any shots being fired, and the suspect surrendered without incident.

A handgun was recovered from the scene, but police have not released the identity of the armed individual. The motive behind his actions remains unclear, and authorities are evaluating the man’s mental health to determine their next steps.

Despite the severity of the situation, no injuries were reported amongst employees or responders throughout the standoff. The plant was temporarily shut down for several hours during the incident but is expected to resume normal operations shortly after police concluded their investigations.

This incident highlights ongoing concerns about workplace safety and mental health, as authorities continue to investigate the circumstances that led to the armed standoff. The police are particularly focused on the suspect’s mental health status, which could provide crucial context as they move forward with their inquiries.

The Stellantis Sterling Heights Assembly Plant, known for producing components vital to the automotive industry, has now faced an unexpected disruption. While operations are set to continue, the management will likely review security measures to ensure the safety of their workforce in the future.

As investigations continue, both local law enforcement and Stellantis officials are collaborating to assess and address the broader implications of the situation. The welfare of employees remains a top priority as the company navigates the aftermath of this incident.
