CCTV footage confirmed the incident. At this time, there are no reported injuries.\nThe individual appears to be a dark-complexioned, male-presenting person with a goatee, wearing a red and black plaid coat with gray sleeves and black pants.\nNo other information is currently available. If you have any additional information about this incident, please contact Investigator Daley at 212-854-6634 and reference case number 26-003742.\nHarm Reduction Strategies:\nNo 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\nMorningside: 212-854-5555\nManhattanville: 212-853-3333\nMedical Center: 212-305-7979\nBe aware of your surroundings, especially when alone at night.\nAvoid walking or biking alone at night. When there are less people around, you are in more danger of being targeted.\nStay alert and tuned in to your environment. Remember that cell phones, earbuds, and other electronic devices divert your attention from your surroundings and block out environmental sound, which increases your vulnerability.\nTrust your instincts. If you feel that you may be in danger, seek out others, a store, or an open CU building that has Public Safety Officers posted. Remember to look for the Red Lion, the logo for the CU Public Safety Safe Haven program, which has screened more than 130 businesses near the Morningside, Manhattanville, and Medical Center Campuses.\nDisclaimer: Clery Crime Alerts (Timely Warning Notifications) are distributed pursuant to the Jeanne Clery Campus Safety Act.
