The Secretary of State said that pro-Palestinian protesters had caused chaos on university campus, but it's unclear if Ozturk was tied to any unrest at Tufts or elsewhere.

Jenna Perlman/Globe Staff) Tufts University graduate student Rumeysa Ozturk, a Turkish national, was detained by federal immigration authorities late Tuesday, according to her attorney and activists.

Tufts University and a lawyer say Immigration and Customs Enforcement took Rumeysa Ozturk, a Turkish national who was maintaining a valid F-1 student visa as a doctoral student, into custody.

Days after Ozturk’s arrest, Secretary of State Marco Rubio confirmed that the U.S. had revoked her student visa, linking her case to the administration’s ongoing crackdown on student activism and implying she is a protester.

Hundreds of protesters gathered near Tufts University’s campus on Wednesday calling for the federal government to release doctoral student Rumeysa Ozturk. It comes after Ozturk's attorney says the Turkish national with a valid student visa was detained by federal authorities wearing masks as she was walking home.

A Tufts University doctoral student arrested by immigration enforcement agents Tuesday was sent to a detention center in Louisiana before a judge ordered the government to keep her in Massachusetts, federal prosecutors said in a court filing Thursday morning.
