A Fairfax County Public Schools bus aide is facing charges after an investigation found he assaulted a child with autism twice while on the way to school.

The mother of the 12-year-old victim was alarmed when her non-verbal son started coming home from school with bruises.

She filed a report and an investigation began. Police said a supervisor reviewed surveillance footage from the bus and saw two encounters between the boy and bus aide.One incident was on October 10 and the other on October 19.

The bus aide has been identified as 57-year-old Hyung Lee of Fairfax.

Two warrants have been issued for assault and battery. Lee turned himself in Tuesday at the Fair Oaks District Station and was taken to the Adult Detention Center.

Police ask anyone who witnesses this kind of behavior towards anyone, but especially toward members of our community who have autism or are or non-verbal, to call 911 immediately.

This is case is not related to the incident where two Fairfax Co. employees were charged after 11-year-old autistic boy was assaulted.
