23 January 2026 U.S. News

DETROIT, Mich. — A disturbing incident unfolded at Denby High School in Detroit when a female student allegedly chased a classmate inside a classroom while wielding a box cutter, prompting swift intervention by school staff and law enforcement. The confrontation, captured in a viral video, shows the student pursuing her peer as a teacher attempts to block her path, using a chair to prevent further escalation.

According to Detroit police, the incident took place on January 22, 2026, though the exact motive behind the altercation remains unclear. The video begins with a student wearing a blue beanie and headphones pointing at another student who has a face mask on. As tensions rise, the masked student retreats before turning and running through the classroom, knocking over desks in the process. The pursuer follows closely behind, brandishing what appears to be a box cutter.

The teacher’s quick thinking is evident as she positions herself near the classroom doorway, using a chair to block the student’s exit and trying to de-escalate the situation. Eventually, the student with the box cutter flees the classroom. Authorities confirmed that the student was arrested shortly after the incident.

This event has raised concerns about safety measures within Detroit Public Schools Community District, which has been under scrutiny in recent years for addressing violence and security in schools. The district has not released a detailed statement but confirmed the student’s arrest and assured the public that the safety of students and staff remains a top priority.

The incident highlights ongoing challenges in school safety nationwide. According to the Centers for Disease Control and Prevention, school violence remains a significant concern, with efforts focused on prevention and intervention strategies to protect students.

Law enforcement officials from the Detroit Police Department responded promptly to the scene. Their swift action ensured that the situation did not escalate further and that the student in possession of the box cutter was taken into custody without additional harm. The department continues to investigate the circumstances surrounding the altercation.

Experts emphasize the importance of mental health resources and conflict resolution programs in schools to prevent such incidents. The U.S. Department of Education has advocated for increased funding and support for these initiatives nationwide, aiming to foster safer educational environments.

The viral nature of the video has sparked widespread discussion on social media platforms and among community leaders about the safety of students and the effectiveness of current school security protocols. As the investigation continues, Detroit Public Schools and local authorities are expected to review policies and consider additional measures to prevent similar episodes.

Parents and community members are encouraged to stay informed through official channels such as the Detroit Police Department and the Detroit Public Schools Community District website. Authorities have also reminded the public to avoid sharing unverified information that could hinder the ongoing investigation.

This incident serves as a stark reminder of the critical need for vigilance and proactive approaches to school safety, combining law enforcement, educators, and community support to protect students and maintain secure learning environments.
