Federal investigators announced that they have launched a civil rights probe into the police shooting of Jacob Blake, a 29-year-old Black man, in Kenosha, Wisconsin.

The US Attorneys Office for the Eastern District of Wisconsin said Wednesday that the investigation will be conducted by the FBI in cooperation with the Wisconsin Department of Justice Division of Criminal Investigation, the agency leading the local investigation.

Authorities had previously provided little information about Sunday's shooting of Blake, which was captured on video by a witness. But after several days of protests in the state, the state's DOJ offered its initial timeline of the shooting. Wisconsin state investigators said that police used a taser to try to stop Blake, before a single officer fired his weapon seven times and injured him.

Blake underwent surgery Tuesday afternoon and his family says he is now paralyzed from the waist down. His shooting -- like several others in recent months -- sparked nationwide demonstrations, with protesters demanding police reform. After George Floyd died in Minneapolis as police pressed a knee to his neck, demonstrations across the country lasted for weeks and in many cities, never stopped.
