The Gem County Prosecutor’s Office filed a criminal charge last week against the Emmett school bus driver who is accused of physically grabbing and verbally confronting a 9-year-old boy in April.

The Idaho Statesman reports, Anna Brown was charged with misdemeanor injury to child on July 31. Emmett Police investigated the incident and reviewed a video of the interaction between Brown and the child. Brown posted a $500 bond on Friday, the same day a warrant was served.

Jennifer Harvey, the mother of the child, told the Statesman that she thought her child was assaulted and reported the incident to police after seeing the video of the driver.

The boy is a third-grader at Shadow Butte Elementary and has some disabilities, including sensory perception disorder.
