Clery Crime Alert Intimidation/Bias Columbia University Public Safety was recently informed of an Intimidation/Bias-motivated incident that occurred on Friday, April 10, 2026, at approximately 11:40 AM on Broadway between West 115th and West 116th Streets. A Columbia student reported walking northbound on Broadway when they encountered an individual walking southbound. The subject was initially shouting antisemitic rhetoric and performing Nazi salutes directed at no one in particular. However, as the student approached, the subject began following the student for approximately half a block while repeating the slurs and gestures. On West 116th and Broadway, the student attempted to cross the street, but the subject verbally confronted the student. A few seconds later, the student was able to cross the street and the subject continued to walk south on Broadway. We believe the student was targeted due to their religious attire (yarmulke). At this time, no NYPD report has been filed by the victim, however, Columbia University Public Safety has given the NYPD notice of the incident. No other information is available currently. If you have any additional information about these incidents, please contact Investigator Pedro Roche at 646-819-9933 and reference report number 26-001331. The subject is shown in the photo below. At the time of the incident, the subject was walking a brown pit bull with a white chest. Harm Reduction Strategies: No one is ever responsible for a crime committed against them. The responsibility lies entirely with the perpetrator. If something happens, we encourage you to report it. Reporting helps protect others and ensures you can access support and services. Report the incident to the Department of Public Safety at Morningside: 212-854-5555 Manhattanville: 212-853-3333 Medical Center: 212-305-7979 Be aware of your surroundings, especially when walking alone. Walk in groups whenever you can. There is always safety in numbers. If you are the victim of a crime, do not engage further with the assailant as that may put you in further danger.

    All 25 reads find Impact present: the student was targeted for religious attire, and engaging further may put you in further danger.

    What the hazard could do to the people in its path.
