Fed up with an increase in crime and pro-criminal policies, former top NYPD official and retired judge George Grasso plans to challenge incumbent Melinda Katz in next year’s Democratic primary for Queens district attorney.

Grasso, 65, worked his way through the NYPD ranks, from street cop, then earned a law degree to become deputy commissioner of legal matters and first deputy commissioner. More recently, Grasso served as administrative judge for criminal matters in Queens Supreme Court and previously as supervising judge for Bronx Criminal Court.
