The attorneys of Jacob Blake, who was left paralyzed after being shot by a police officer last summer, have filed a federal civil rights lawsuit against the officer accusing him of using excessive force.

The lawsuit, filed Thursday by civil rights attorney Ben Crump in the U.S. District Court for the Eastern District of Wisconsin, accuses Kenosha, WI, Officer Rusten Sheskey of shooting Blake six times at point blank range without cause, UPI reports.

Blake was shot by Sheskey on Aug. 23.

The police union has maintained Blake resisted arrest and was armed with a knife during the shooting. Blake, his family, and attorney's dispute this.

The Kenosha County (WI) District Attorney Michael Graveley said Officer Rusten Sheskey was justified in his use of deadly force. The other officers at the scene also were not be charged.
