National News Feds sue NYC over Rikers Island jail violence December 18, 2014 18:59 GMT By JAKE PEARSON and TOM HAYS Associated Press NEW YORK (AP) -- A spokeswoman says New York City Mayor Bill de Blasio (dih BLAH'-zee-oh) is committed to reform at the troubled Rikers Island jail complex. The comment came in response to a lawsuit filed by federal prosecutors seeking to speed reforms at Riker Island. The lawsuit was filed Thursday to address what a Justice Department investigation found was a culture of violence against young inmates. On Wednesday, de Blasio announced the end of solitary confinement for 16- and 17-year-old inmates. Prosecutors identified 73 recommendations to curb the violence. In court papers, Attorney General Eric Holder and Manhattan U.S. Attorney Preet Bharara (buh-RAH'-ruh) wrote that despite four months of negotiations with the city, federal prosecutors "have been unable to reach agreement as to lasting, verifiable and enforceable reforms."
