A U.S. citizen on her way to a medical appointment in Minneapolis was dragged out of her car and detained by immigration officers, according to a statement released by the woman on Thursday, after a video of her arrest drew millions of views on social media.

Aliya Rahman said she was brought to a detention centre where she was denied medical care and lost consciousness. The Department of Homeland Security said she was an agitator who was obstructing ICE agents conducting arrests in the area.

That video is the latest in a deluge of online content that documents an intensifying immigration crackdown across the midwestern city, as thousands of federal agents make arrests amid protests against what local officials have likened to a “federal invasion.”

Rahman says she was on her way to a routine appointment at the Traumatic Brain Injury Center when she encountered federal immigration agents at an intersection. Video appears to show agents shouting commands over a cacophony of whistles, car horns and screams from protesters.
