A federal judge on Wednesday formally approved a landmark settlement of a lawsuit over conditions at New York City's Rikers Island jail that calls for a monitor, 7,800 cameras in the facility and an array of reforms to try to cut down on violence.

Manhattan U.S. District Judge Loretta Swain also OK'd $6.5 million in legal fees for private lawyers who pressed the suit, which was eventually joined by Justice Department lawyers from the office of Manhattan U.S. Attorney Preet Bharara.

In addition to more cameras in the facility, the settlement calls for some guards to wear body cameras; improved training, oversight and discipline of correction officers; and new rules for the government to handle adolescents.

Swain said it would "provide an important example for other correctional systems around the country."
