NEW YORK – A Brooklyn high school science teacher decided lessons about atoms and rocks weren’t enough for his students.

So he took a number of them, prosecutors allege, to a sex club and nude beaches.

Newsday reports:

Sean Shaynak, a Brooklyn Technical High School teacher, was arrested last month and accused of sending a sexually explicit photo to a student. He pleaded not guilty to those charges.

But as investigators reviewed evidence in the case, including hundreds of photographs and videos, they determined that he had also victimized six other girls ranging in age from 13 to 19, Brooklyn prosecutors said.

Upon further investigation, Shaynak was charged with 36 counts of crimes against minors. The accusations include “kidnapping, criminal sexual act, obscenity and forcible touching.”

Shaynak, who pleaded not guilty, could go to prison for 25 years if convicted on just one of the charges. The judge set bail at $750,000 bond or $500,000 cash, according to Newsday.

“He brought her to a sex club out of state where he performed sex acts on other people and other people performed sex acts on him in the presence of the victim,” Brooklyn Assistant District Attorney Joseph Mancino says, adding that Shaynak bought her cigarettes and took her on a terrifying car ride during which he screamed that she couldn’t tell her parents.

Shaynak also took one teenage girl to a New Jersey nude beach, gave her “Jack Daniels and tequila to the point where she passed out” at his house, and traded over 10,000 text messages with her, Mancino said.

The teacher also allegedly attempted to persuade a student to have a lesbian relationship with another student. He had a threesome with others, according to the New York Post.

“He would routinely give her 100s in his class even though she turned in work with no answers,” the prosecutor said of a another Brooklyn Tech student whom he had sex with and also raped.

Shaynak is in a union-created “rubber room” and continues to receive his full pay, pending the outcome of court proceedings.

According to Newsday, the teacher’s annual base pay is $52,744.

“The fact that our system continues to pay and even protect these predators — with many parents having no idea that their children are in danger — defies common sense,” Campbell Brown, founder of Partnership for Educational Justice tells the New York Daily News.
