GOODLETTSVILLE, TN (AP) - Authorities in Tennessee say they've arrested a woman accused of raping a boy she was babysitting.

News outlets report 20-year-old Demetriona Harper was arrested Monday and charged with felony child rape.

A Metro Nashville police arrest affidavit says Harper was babysitting a 12-year-old boy on Oct. 17 when they went into his room to play video games.

The affidavit says she touched the boy and had sexual intercourse with him. It says that during Harper's interview with police she admitted to letting things "go too far" and that she made a mistake.

It's unclear whether Harper has an attorney who can comment on her behalf.
