In New York, police have released security camera footage showing an undercover officer slamming retired tennis star James Blake to the ground. The footage shows Blake, who is biracial, standing outside his Manhattan hotel when Officer James Frascatore approaches him, wraps an arm around his neck, tackles him down, digs his knee into his back and handcuffs him. Police say they mistakenly identified Blake as a suspect in a credit card fraud probe. New York City Mayor Bill de Blasio and Police Chief William Bratton have personally apologized to Blake. Officer Frascatore has a pattern of excessive force complaints against him. He has been accused of punching and pummeling a man in his own driveway; punching a man in the face after stopping him for a broken tail light; punching a man outside a bodega and calling him a racial epithet; and manhandling a woman who told The New York Times, “He was really rough … It was akin to a kidnapping.” James Blake has called for Officer Frascatore to be fired.
