NYPD officers arrested Council Member Chi Ossé on Apr 22 during a protest against the eviction of Carmella Charrington from her Bed-Stuy brownstone. Video shows officers throwing Ossé face-down to the pavement. Ossé and family allege deed theft; the AG's office and property purchaser dispute the characterization. Mamdani called the footage "incredibly concerning" and reached out to Commissioner Tisch. On Apr 24, Mamdani launched the Office of Deed Theft Prevention housed at DOF. Second NYPD friction point in two weeks (after narcotics disbandment Apr 14). PBA framing: mayor "prejudging" another arrest.
