Fresh protests were set to erupt nationwide after a woman was fatally shot by a U.S. immigration officer in Minneapolis, as Minnesota officials accused federal authorities of sidelining local investigators from the case.

Protest organizers said they expected to hold more than a thousand weekend demonstrations following the killing of motorist Renee Good, 37, by an Immigration and Customs Enforcement (ICE) agent on Wednesday.

Officials in the midwestern state of Minnesota said their law enforcement agencies have been shut out of the investigation into the shooting.

A local prosecutor said Friday that federal investigators had taken Good's car and shell casings from the scene.

The Trump administration has sought to paint Good as a "domestic terrorist," insisting that the agent who fatally shot her was acting in self-defense.
