A member of the grand jury that declined to indict the white Missouri police officer who fatally shot an unarmed black 18-year-old sued the prosecutor in the case on Monday, criticizing the way evidence was presented to grand jurors and seeking court permission to speak publicly about the way the case was handled.

The lawsuit was filed in federal court in St. Louis against St. Louis County prosecutor Robert McCulloch by the grand juror, whose name was withheld and was referred to as "Grand Juror Doe."

The lawsuit relates to the Aug. 9 shooting of Michael Brown by officer Darren Wilson in the St. Louis suburb of Ferguson. Brown's death and the grand jury's decision not to indict Wilson triggered months of protests over police treatment of African-Americans in the United States.
