From an article:
Police tell the Telegram & Gazette that a 10-year-old boy sitting next to the window that was struck said he felt something strike the side of his head, but paramedics did not find he had any injury.
School safety liaison Robert Pezella said the elementary school bus carrying 18 students was two stops from the end of its route when it was struck. He said the students were frightened, and parents came to pick them up.
Police said the bus driver was unaware of what happened.
Police said a witness told officers a man pointed an object at the bus, and the window shattered. The man reportedly ran away.
