Email sent to the Columbia community from Acting President Claire Shipman at 7:24 pm on September 9, 2025:

Dear members of the Columbia community,

Today, we were made aware of a troubling situation involving a Columbia graduate student on the streets near our Manhattanville campus, who was approached by several individuals who stated they were federal agents. Our student was detained on the street, handcuffed by these individuals, and then subsequently released. The individuals did not provide identification legible to the student. We are providing support services to our affected student.

This incident is deeply disturbing, and the University is working to obtain additional details, including any video evidence to share with local law enforcement.

It also serves as a strong reminder to our community of the many resources available through our Public Safety office to help keep you safe on and off campus. From our shuttle service to the frequent Public Safety patrols, every member of the Columbia community should review these available resources and know how to access them in case of an emergency.

Additionally, the University has clear protocols on interactions with Immigration and Customs Enforcement (ICE) officers on campus. Those protocols can be easily accessed online.

It is vital that every member of our community feel safe, on and off campus. I encourage everyone to look after one another, and if you see something, say something. Alert our Public Safety team at 212-853-3333 or call 911.

Sincerely,

Claire Shipman
Acting President, Columbia University in the City of New York
