A Valhalla High School student claims a music teacher threatened her with bad grades, unless she had sex with him.

The allegations are outlined in a lawsuit filed by the student against the teacher, school district and high school under the Child Victims Act in State Supreme Court.

The student, identified as Jane Doe, claims the abuse began in the spring of 1985 when she was 15 years old and continued until the fall of 1986. At one point, she claims the teacher raped her.

She said the teacher knew she needed a scholarship to go to college and bad grades would decrease her chances.

The teacher, Jeffrey Dulitz, told News 12 he was not aware of the lawsuit and called the allegations absolutely false and ludicrous.

The school district did not know of the lawsuit as well.
