In 2012, a Queens man said, Officer James Frascatore pulled him over for a broken taillight, opened his car door and punched him three times in the mouth, unprovoked.

The following year, another Queens resident claimed, Officer Frascatore punched him in the stomach several times outside a bodega and called him a racial epithet.

Those accounts, both made by black men, came to light after a rough arrest by the same officer on Wednesday in which he wrapped an arm around the neck of the retired tennis star James Blake and threw him to the sidewalk after mistaking him for a suspect in a credit card fraud investigation.

The New York Police Department released surveillance video of the arrest on Friday, offering a minute-long glimpse of the manhandling of a biracial sports star by a white plainclothes officer that compelled officials to swiftly strip the officer of his gun and badge.
