A worker at an upstate New York maximum-security prison has been arrested on charges she helped two convicted killers escape.

State police said Friday prison tailor shop worker Joyce Mitchell will be arraigned on charges of first-degree promoting prison contraband and fourth-degree criminal facilitation, both felonies.

District Attorney Andrew Wylie said earlier the contraband didn't include power tools used by the men as they cut holes in their cell walls and a steam pipe to escape through a manhole last weekend.

Law enforcement officers continue to search for the escapees, concentrating Friday in a rural area near the prison.

Mitchell's family has said she wouldn't have helped the convicts break out.
