A 13-year-old boy pleaded guilty Friday to raping a young girl inside a Manhattan library.
He was facing first-degree sexual abuse charges for the September 4 incident.
Police say the teen approached the 8-year old girl at the Countee Cullen Public Library on West 136th Street.
Investigators say he convinced her to go into a unisex bathroom with him, where he assaulted her.
The boy has been taken into custody by the Administration for Children's Services.
