A 5th grade teacher at a public school in Queens, N.Y., was arrested after authorities heard audio of an alleged assault against a 10-year-old autistic boy last month.

Teacher Alexander Perry accused the boy of cheating. In the audio, Perry appears to become increasingly agitated before striking the child repeatedly.
