An ROTC teacher at a Manhattan high school was arrested Tuesday and charged with groping a 14-year-old girl.

Authorities say Darryl Lynch, a 55-year-old resident of Bridgeport, Conn. who has taught at the High School of Graphic Communication Arts since 1997, groped the student on school grounds earlier this month.

The alleged victim told a guidance counselor, who then told the principal.

Lynch was charged with sexual abuse, forcible touching and acting in a manner to injure a child.

Schools Chancellor Dennis Walcott said in a statement, “I am outraged by these charges, and have no tolerance for adults who betray the trust of their students and school communities. With the changes we have announced, any individual who has an inappropriate relationship with a student will be removed from the classroom as soon as allegations surface — and moving forward, be barred from teaching in our schools if those charges have merit."

Lynch, who was still awaiting arraignment late Tuesday, is the sixth Department of Education employee to be arrested this month for sex crimes involving children.

Manhattan teacher's aide Gregory Atkins, Queens teacher Wilbert Cortez and Queens teacher's aide Brett Picou were accused of molesting children in their respective schools.

Bronx substitute teacher Chukwuma Duru was accused of forcibly touching a student.

Brooklyn teacher's aide Taleek Brooks was accused of possessing child pornography and producing child pornography in a classroom.

Another three Department of Education employees were accused this month for inappropriate yet non-sexual conduct with children.
