New details have emerged in the case of Sandra Amezquita's rough arrest last Saturday that was in part captured on video. In the video, an NYPD officer slams Amezquita, who is pregnant, belly-first into the ground. She and her attorney now say cops beat her belly with a baton.

An NYPD officer was filmed violently throwing a pregnant woman to ground early Saturday morning. Sandra Amezquita, who is five months pregnant, reportedly suffered vaginal bleeding after the incident, and her arms and stomach remain bruised.
