Crime Alert Headphone Thefts Columbia University Public Safety has been notified by the NYPD of a series of headphone thefts that occurred near the Morningside and Manhattanville campuses over the weekend. The incidents involved a group of male-presenting teenagers riding CitiBikes and wearing masks. One individual was often seen sitting on the front basket of a bike. The suspects reportedly approached pedestrians from behind—either on the street or sidewalk—and removed headphones from their heads. Fortunately, no injuries have been reported. Two incidents were reported directly to Public Safety. One occured on Sunday, August 31 at approximately 7:00 p.m. on Broadway between West 118th and West 119th Streets.. The second incident occurred on Monday, September 1 at approximately 7:21 p.m. on Broadway at West 131st Street. We strongly encourage anyone who experiences or witnesses a crime to report it to both Columbia University Public Safety (Morningside (212-854-2797 / Manhattanville (212-853-3301) / Medical Center (212-305-8100) and the NYPD. Timely and accurate reporting helps enhance awareness of incidents occurring in and around our campuses, enabling more effective resource allocation and communication with the community. Safety Tips Stay aware of your surroundings and minimize distractions. Devices like cell phones, earbuds, and other electronics can reduce your ability to hear and observe what’s happening around you, increasing vulnerability. Headphones worn on the head are particularly easy to grab and have been frequent targets in recent incidents. Be cautious of scooters, bicycles, or other vehicles that pass unusually close to the sidewalk. This behavior may indicate an attempt to approach pedestrians quickly and unexpectedly. DISCLAIMER: Clery Crime Alerts (Timely Warning Notifications) are distributed pursuant to the Jeanne Clery Campus Safety Act. Columbia University is required to alert the campus community when certain crimes occur in our Clery Act defined campuses that represent a serious or continuous threat to the community.

Message elements

How the first alert is built

To check this alert, SuperGrok Heavy 4.5 (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

  • Impactpresent18/25

    Final assessment

    An 18 to 7 majority finds Impact present: the line that no injuries have been reported is treated as a harm statement. Dissenters say that line only denies injury.

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.
