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

Friend of Ozturk said that there is a fundraiser people can donate to in order to support the Turkish national while she is detained. 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 was suddenly arrested by plainclothes federal agents Tuesday in an incident captured by a surveillance camera.
