Police say a suburban New York bus aide fractured a developmentally disabled 5-year-old boy's arm.

Richard Mason did not comment to reporters after being released without bail Thursday following his arraignment in Suffolk County Court on Long Island. He is being represented by the Legal Aid Society, which does not comment on pending cases.

Suffolk County police say the Acme Bus Corp. aide attempted to discipline the boy during a bus ride on Monday afternoon in Commack. Police say Mason grabbed the boy's arm and twisted it behind his back.

The child was later determined to have a fractured arm.

Mason was charged with assault and acting in a manner to injure a child.

A message left for the bus company was not immediately returned.
