A judge ruled New York City is now in contempt over "grave" conditions at the Rikers Island prison complex, with a federal takeover of the system now seen increasingly as likely in a years-long legal battle.

The judge said the city had placed incarcerated people in “unconstitutional danger” by failing to comply with 18 separate provisions of court orders pertaining to security, staffing, supervision, use of force and the safety of young detainees.

A judge's scathing ruling Wednesday moves New York City's troubled Rikers Island jail complex a step closer to a federal takeover. Judge Laura Taylor Swain found the city and the Department of Correction in civil contempt over 18 separate claims of failing to rectify use of force and safety issues.
