New York State Police say they've arrested Clinton Correctional Facility worker Joyce Mitchell and charged her with "providing material assistance" to two convicted killers who escaped from the prison last weekend.
The arrest of Mitchell, 51, comes after several days of speculation that a prison employee might have played a role in the escape of Richard Matt and David Sweat.
The State Police say: "Mitchell was charged with Promoting Prison Contraband 1st Degree, a class D Felony, and Criminal Facilitation 4th Degree, a class A misdemeanor."
We're expecting a news conference at 6:30 p.m. ET; we'll update this post with news from that event.
On Wednesday, New York Gov. Andrew Cuomo confirmed to reporters that a female prison worker had been interviewed as part of the investigation. At the same news conference, officials said they believe there's a chance that Sweat and Matt, who remain at large, might have have headed to a Vermont camp.
