Tufts University international graduate student Rumeysa Ozturk was taken into custody by federal authorities Tuesday.

The U.S. Department of Homeland Security accused Ozturk, a Turkish national, of "activities in support of Hamas."

Instead, the 30-year-old was arrested and physically restrained by immigration officers near her apartment, close to Tufts University’s Somerville campus where she was a PhD student, lawyer Mahsa Khanbabai told CNN.
