MINNEAPOLIS (AP) - Hennepin County Attorney Mike Freeman has asked a state agency to expand its investigation into the November fatal shooting of a black man by Minneapolis police.

Freeman says his office has discovered "that a number of things were not completed," so the case was returned to the Minnesota Bureau of Criminal Apprehension. He would not elaborate.

Twenty-four-year-old Jamar Clark was shot by a Minneapolis officer on Nov. 15 during what authorities said was a struggle. Some who said they saw the shooting have said that Clark wasn't struggling and was handcuffed.

Freeman also disclosed that he had surgery Saturday after slipping on the ice and tearing ligaments in his leg. But he still hopes to have a decision by the end of March on whether or not the officers will be charged.
