An NYPD officer fired his gun while storming Columbia University’s Hamilton Hall Tuesday night during the operation to oust anti-Israel protesters who illegally took over the building.

The cop did not appear to aim the weapon at anyone, and no one was injured, said Douglas Cohen, a spokesperson for Manhattan District Attorney Alvin Bragg’s office.

The shooting is under review by the DA’s Police Accountability Unit, he added.

The cop fired the weapon as more than 100 Emergency Service Unit officers swarmed the Ivy League building April 30 to clear out the roughly 50 protesters who broke inside the night before.

The NYPD blocked journalists from getting too close to the break-up, instead relegating them to a nearby area where they witnessed the suspects be walked out in zip-tie handcuffs and placed into department buses.
