A Columbia University student was detained by federal agents Thursday morning at one of its residential buildings, the university’s acting president said.
“Our understanding at this time is that the federal agents made misrepresentations to gain entry to the building to search for a ‘missing person,'” Claire Shipman wrote in an email to the Columbia community.
Manhattan Borough President Brad Hoylman-Sigal claimed in a social media post that the agents “impersonated NYPD with fake badges and a phony missing persons bulletin for a 5 year old girl.”
“The level of civil rights violations that took place is staggering,” he wrote.
CBS News New York has reached out to the Department of Homeland Security for comment.
Shipman didn’t provide details of exactly where the incident occurred, saying only it took place at 6:30 a.m.
She emphasized that law enforcement agents are required to have a warrant or subpoena to enter the university’s private property, including housing areas.
“An administrative warrant is not sufficient,” she wrote.
“I want to know if they had a warrant”
Gov. Kathy Hochul expressed concern about the detention.
“I want to know if they had a warrant. What the conditions of that arrest were. And we’re still looking for more information, but, to misrepresent who they are, I’ve said they’re out of control,” Hochul said. “And if that is the case, and still, I have to get all the details, because this is newly unfolding.”
City Council Speaker Julie Menin and majority leader Shaun Abreu, both Columbia alumni, said they’d been briefed and had offered the university their assistance, adding “ICE has no place in our schools and universities.”
New York City Public Advocate Jumaane Williams said that misrepresenting their identity and purpose to gain entry to the building would be a “despicable and lawless act.”
“This rogue agency has no regards for our policies, our laws, or our rights,” Williams said.
“This exhibit of the Trump Administration’s lawless actions — which are rarely supported by legitimate warrants or subpoenas — is yet another reminder that Columbia University and other institutions must enhance the protections and policies they utilize to create a safe environment for those they serve and employ,” Rep. Adriano Espaillat said.
Read the full email to students
Here’s Shipman’s full email to the students:
Dear members of the Columbia community:
This morning at approximately 6:30 a.m., federal agents from the Department of Homeland Security entered a Columbia Residential building and detained a student. We are working to gather more information, working to reach the family, and providing legal support.
Our understanding at this time is that the federal agents made misrepresentations to gain entry to the building to search for a “missing person.” We are working to gather more details.
It is important to reiterate that all law enforcement agents must have a judicial warrant or judicial subpoena to access non-public areas of the University, including housing, classrooms, and areas requiring CUID swipe access. An administrative warrant is not sufficient.
If law enforcement agents seek entry to non-public areas of the University, ask the agents to wait to enter any non-public areas until contacting Public Safety. Public Safety will contact the Office of the General Counsel to coordinate the University’s response. Do not allow them to enter or accept service of a warrant or subpoena.
We will update our community as additional information becomes available.
Columbia University has been a flashpoint
Columbia University has been a flashpoint since campus protests broke out after Hamas attacked Israel, killing civilians and taking hostages on Oct. 7, 2023.
Israel’s retaliation and subsequent war against Hamas in Gaza drew widespread criticism and prompted protests on Columbia’s campus. Those protests spread nationwide.
In March 2025, Mahmoud Khalil, a pro-Palestinian activist and graduate student involved in the protests at Columbia, was picked up by federal agents at his Manhattan apartment, setting off a lengthy legal battle as the Trump administration tried to deport him.
