A Brooklyn high school teacher who was already under indictment for sending a lewd photo to a student is now facing dozens of new charges.
Sean Shaynak, 44, was a math and science teacher at Brooklyn Tech.
Brooklyn District Attorney Kenneth Thompson announced a new 36-count indictment against him on Tuesday.
Thompson says the new charges come after investigators found evidence on Shaynak's computer that he victimized six other female students aged 13 to 19 between 2011 and this year.
The new charges include kidnapping and criminal sexual act.
Included in the indictment are allegations Shaynak took a 15-year-old girl to a nude beach, exchanged thousands of text messages with students, had sex with an 18-year-old student without her consent and requested two underage girls to engage in sex with each other.
Shaynak faces up to 25 years in prison on the top charge.
Brooklyn Tech students who spoke with NY1 say the teacher was noted for his frequent unusual behavior.
Some parents are also now questioning the safety of students.
"He'd come to parties sometimes, show up at student parties and show up at student events and stuff like that. Once he came dressed as a girl and whatnot, he did some weird stuff sometimes, but everybody thought he was just a guy that liked to party," said one student.
"He would smoke with his students, he would -- he was inappropriate. He was like a teenager, he was basically a teenager. He did everything a teenager would do," said another student.
"I am very concerned I mean this is supposed to be a really good school," said one parent.
In a statement, the Education Department pointed out that Shaynak was reassigned immediately after his initial arrest and would not have any more contact with students.
