CHERRY HILL, N.J. (CBS) — Stuart Chaifetz of Cherry Hill, posted an alarming video on Youtube, Monday.

In it, he alleges school aides and teacher Kelly Altenburg had bullied his 10-year-old son, Akian, who has autism, while at Horace Mann Elementary.

His proof, he says was the six hours of audio from a recorder Chaifetz stuck in his son’s pocket on February 17th.

You can hear school officials making inappropriate comments and yelling at a student.

“I was devastated and heart broken,” said Chaifetz.

Tuesday night, Chafietz made another video where he calls the Cherry Hill School District to show his son’s teacher is still employed.

Friday afternoon, the District released a statement saying the investigation continues and quote, “all individuals working in the classroom on the date in question have either been placed on leave…or no longer work for the District.”

The teacher on leave, Kelly Altenburg, was transferred to another school and her attorney, Matthew Wieliczko, says she is on leave.

But, Wieliczko, says his client’s voice is not on the recordings and he says Altenburg was not even in the classroom when comments such as, “you are an (expletive) and shut your mouth,” were made.

“Mrs. Altenburg was in a meeting that morning,” said Wieliczko

According to Altenburg’s attorney, she has received nothing but excellent evaluations in her 23 years as a special education teacher.
