Allegedly pervy Brooklyn schoolteacher Sean Shaynak is back in the news this week, after a former student sued the Department of Education for failing to put a stop to his notorious behavior. Which, according the the student, included exposing himself to her, taking her to the Museum of Sex, trapping her in a car, and driving recklessly while on a "date," an act she justifiably felt threatened her life.

The allegations against Shaynak, who was formerly employed at Brooklyn Tech, are mounting, with prosecutors alleging he took a student to a sex club and nude beach, harassed another via text message, sent students explicit photos, inappropriately touched, groped and kissed students, gave teens cigarettes and alcohol, and tried to convince underage girls to have sex with each other. He was arrested in August and slapped with a slew of criminal charges, including criminal sexual acts, endangering the welfare of a child, and sexual abuse.

The lawsuit against the DOE, which was filed on Saturday, is the first implicating the city. According to the Post, it was filed on the behalf of an of-age female student who had a sexual relationship with Shaynak, claiming the teacher repeatedly harassed her and obsessed over her when she tried to break things off with him. Most terrifyingly, the suit claims Shaynak drove her to a Halloween party—while dressed in a schoolgirl's outfit—yelled at her "in a threatening tone," then drove the wrong way while "speeding and driving recklessly through traffic." The student managed to escape after "silently praying for her life."

The suit alleges that Brooklyn Tech Principal Randy Asher and other school officials were aware of Shaynak's behavior, but did not stop him. The DOE also hired Shaynak despite a 2005 arrest in which he was accused of beating up an 11-year-old—that charge was dismissed.

Shaynak has pleaded not guilty to the charges against him. The City Law Department has not yet provided us with a statement regarding the suit.
