3rd Knife Rap For High School Gym Teacher
`A third student stepped forward yesterday claiming a Queens gym teacher threatened him with a knife in class.
The 17-year-old autistic boy told investigators that Mark Omeltchenko, 45, pointed a knife at his neck and put him in a headlock during the same workout session in which the teacher allegedly threatened two other students, law-enforcement sources said.
The new complaint says the boy – like the two girls, ages 14 and 15, in his Aviation HS class – didn’t want to participate in drills Thursday morning and that set off the teacher, according to a spokesman for District Attorney Richard Brown.’
