A Manhattan Supreme Court justice on Wednesday dismissed all charges against an engineer indicted in 2018 alongside former city employee Ifeanyi “Manny” Madu in a bribery scheme, dealing a blow to the Manhattan District Attorney’s Office in the wake of a scandal over withholding of evidence by a top assistant DA.

“While the remedy of dismissal may be unusual or extreme, so too are the facts of this case,” Justice Michael Obus wrote in the 17-page dismissal order for Kyriacos Pierides, who had been charged with bribery and corrupting the government.
