An Ursuline Academy of Dallas teacher has been arrested on an accusation of inappropriate relationship with a student, Dallas police said.

David B. Novinski, 35, turned himself into police Monday at Lew Sterrett Justice Center and has since posted bond, said his attorney David Finn.

Police received a report that a teacher had engaged in sexual contact with a 17-year-old student at the private Catholic all-girls school. A relationship allegedly began Feb. 10 and an offense report was filed last week, Dallas police said.

School administrators said they received a report of improper conduct in June and contacted the state child abuse hotline.

The school was conducting an internal investigation, and the accused teacher has been suspended.

Texas law states that sexual contact between a teacher and student is illegal even if the student is of consensual age.
