A Treasure Coast teen accused of having sex with her underage girlfriend is back in jail after prosecutors withdrew a plea deal.

Authorities say 19-year-old Kaitlyn Hunt was booked into the Indian River County Jail Monday night. She remained in jail Tuesday morning, charged with two counts of lewd and lascivious battery on a child.

The state attorney's office pulled its plea offer Monday following allegations Hunt violated her pretrial conditions and contacted the girl identified as the victim in the case.

Indian River County Sheriff's Sgt. Thomas Raulen told Scripps Treasure Coast Newspapers that the bond company that posted Hunt's bail brought her to jail.

Authorities say Hunt had sex with her then-14-year-old girlfriend last year. Hunt argues the sex was consensual.  She was ordered to have no contact with the younger girl, but prosecutors say Hunt has been sending mulitple text messages, including nude pics of herself to the girl. 

Prosecutors also claim Hunt's mother has asked the other teen to delete the text messages so that nobody would find out they were sent.

Hunt was due back in court on Tuesday afternoon for a hearing regarding the alleged pre-trial release violations.
