Michael Schock, 28, filed the claim this week against the city of Lafayette, the police department, the two officers involved in the shooting and the Contra Costa Sheriff's Department, according to a story in the Contra Costa Times.
Schock's attorney told the Times his client was armed only with a broom when he was shot. He said Schock was having a "psychotic break" when he thought officers were harming his brother-in-law and charged at them.
Schock was shot three times but survived.
So far, Lafayette officials have not commented on the case.
Schock is out of custody. He has a preliminary hearing on Nov. 4 on charges of obstructing an officer, exhibiting a deadly weapon and making criminal threats.
