“ICE HSI (Homeland Security Investigations) made this arrest in accordance with the State Department’s revocation of Doroudi’s student visa. This individual posed significant national security risk concerns,” the statement read. According to The Crimson White, the DHS spokesperson did not explain what those national security risk concerns entailed.

In a statement, DHS said he posed significant national security concerns, but declined to clarify those concerns when asked.

Two more nonresidential students have been detained by ICE as the Trump administration continues to arrest individuals it considers supportive of Hamas.
