U.S. Magistrate Judge Robert C. Mitchell today announced a federal grand jury handed up a five count indictment of former Pittsburgh police chief Nate Harper. Assistant U.S. Attorney Robert Cessar said the indictment included one count of criminal conspiracy. Judge Mitchell described the four other counts as “tax problems.” The grand jury foreman said 17 members were present and at least 12 voted to indict. Mr. Cessar motioned for an arrest warrant. At an afternoon initial appearance and arraignment before U.S. Judge Mitchell, Mr. Harper pleaded not guilty as is standard at this stage of federal proceeding. He appeared in a brown suit with attorneys Robert DelGreco and Robert Leicht, who said they will continue to represent him.
