Tellez never checked on the welfare of the injured boy before starting back along the route. The boys were then dropped off at their stops without any other incident, according to investigators.
The injured boy's parents said he had a cut on his lip and injury to his hip, the Republic reported.
“The irresponsible behavior by this bus driver put several students in harm’s way,” Mesa police Chief Ramon Batista said in a statement. “We are thankful that our school district quickly reported this incident to our officers.”
Tellez was arrested and charged with child abuse. A status conference in court is scheduled for Oct. 23.
He has worked as a bus driver for the district since September 2018. He is on unpaid leave and will likely lose his job. A ruling on his termination will be decided by the school board Oct. 24.
