NEW YORK - Prosecutors say a man has admitted to sexually abusing a 2-year-old girl in the bathroom of a New York City park.

Manhattan District Attorney Cyrus Vance, Jr. says 32-year-old Jason Carroll pleaded guilty Wednesday to charges of criminal sexual act and possession of a sexual performance by a child.

Prosecutors say Carroll was supposed to be taking care of the young girl when he brought her into a bathroom in Riverside Park in September 2013 and sexually assaulted her. Two witnesses called police and Carroll was arrested at the scene.
