Grand jury refuses to indict NYPD Det. Hassan Hamdy in shooting of Noel Polanco

A Queens grand jury today declined to indict a NYPD cop who gunned down an unarmed National Guardsman last year, The Post has learned.

The jury returned a no true bill in the case against ESU cop Hassan Hamdy, who shot Noel Polanco in October during a traffic stop on the Grand Central Parkway, a law-enforcement source said.

Hamdy, with the Emergency Services Unit, pulled over Polanco on Oct. 4, and claimed the 22-year-old Guardsman reached to the floor of the car despite his warnings to keep his hands on the wheel, sources previously said. The elite detective feared for his life, the sources said.
