Rumeysa Ozturk, a Turkish doctoral student at Tufts University, was taken into custody by immigration officials on March 25.

Friends of Tufts University graduate student Rumeysa Ozturk, who was arrested in Somerville last week by Immigration and Customs Enforcement agents, are speaking out.

Ozturk filed her case in Massachusetts, where she was arrested, but authorities moved her to Vermont and then Louisiana. She alleged in her court petition that she was targeted in retaliation for exercising her right to free speech under the First Amendment of the Constitution.
