The city's prison system is changing the way it disciplines mentally ill prisoners.
Correction officials say they'll rely more on counseling and therapy instead of solitary confinement.
They say solitary confinement often makes mentally ill prisoners act worse.
This is welcome news for advocacy groups fighting for inmate rights.
Authorities say they want to ensure everyone's needs are met.
"It will be in a secure setting," said New York City Correction Commissioner Dora Schriro. "But the purpose is to give them the services and support that they need so as to be more successful while they're incarcerated in jail as well as when they return back to the community."
Correction officials hope to have the new rules in place by July.
