Actor Michael Pitt, known for his TV roles on “Boardwalk Empire” and “Dawson's Creek,” is accused of sexually assaulting his ex-girlfriend, choking her, and attacking her with a cinder block and a piece of lumber at his New York City home, according to a grand jury indictment. Pitt, 44, whose lawyers denied the allegations, was arrested Friday on nine counts including first-degree sexual abuse, criminal sexual acts, assault, attempted assault and strangulation. The indictment cites four incidents between April 2020 and August 2021 at Pitt's home in the Bushwick section of Brooklyn.
