Federal prosecutors are suing New York City over the treatment of teenagers jailed at Rikers Island. The move follows a scathing Justice Department report which found a “deep-seated culture of violence” against young prisoners and recommended over 10 pages’ worth of reforms. Earlier this week Mayor Bill de Blasio delivered a news conference at Rikers announcing the end of solitary confinement for 16- and 17-year-olds. But federal officials say the reforms are not coming fast enough, noting that 18-year-olds still face prolonged periods in solitary.
