EL SEGUNDO, Calif. — A UCLA international student was detained by Customs and Border Protection while attempting to enter the U.S. from Mexico, the university's Vice Chancellor for Strategic Communications Mary Osako reported Thursday.

"The student remains in the custody of CBP and we are actively working to learn more information," Osako said in a statement. "Our international students are an essential part of our Bruin community, and we remain fully committed to supporting their ability to learn and thrive at UCLA."

The Los Angeles Times reported that the student — whose name was not released — was taken into custody Wednesday night, which was confirmed by faculty members and students who organized a campus rally in her support Thursday evening.

It is unclear what led to the student's detention.

In late March, Secretary of State Marco Rubio said the U.S. has revoked as many as 300 visas and potentially more, as the Trump administration ramps up its campaign to crack down on immigration — including foreign-born students who have engaged in political activism at America's universities.
