FAIR LAWN - A Fair Lawn High School teacher has been placed on leave while the school district investigates a classroom video that depicts him screaming at a special education student. And a Kane In Your Corner investigation finds this may not be the first time the teacher’s behavior has been an issue.

The video, which has gone viral on YouTube, shows the teacher telling the student, “Shut your mouth. Don't you ever for one second in your life think that you're going to tell me anything. You are my God damned student, you get that? I'm your teacher. Don't ever tell me what to do. You get it now?"

After the student returns to his desk, the teacher tells him to “Go cry to your counselor!”

Fair Lawn Schools superintendent Bruce Watson says, “We deeply regret the actions that took place in the classroom,” and says the teacher has been placed on leave while the district conducts a full investigation. Watson would not release the teacher’s name but News 12 New Jersey has confirmed he is Bill Scarnaty, a teacher and former coach, who also competes in semi-pro bodybuilding.

Some parents tell Kane In Your Corner there have been complaints about Scarnaty’s classroom behavior for years. One parent, who asked not to be identified, says Scarnaty has told his daughter
“to shut up, she asks too many questions and he doesn't want to hear her voice anymore.”

Scarnaty’s behavior may have been the cause of his sudden resignation as Fair Lawn High School’s baseball coach in 2008. Sources within the school district say the resignation came after Scarnaty was accused of kicking a student.

Kane In Your Corner attempted to contact Scarnaty but he has not returned calls.
