A Maine bus driver who made students wear duct tape over their mouths for being loud is no longer behind the wheel of a bus. The bus driver at Surry Elementary School was removed from her position last week after two fourth-grade girls told their principal the driver made them put the tape over their mouths. The Portland Press Herald reported that neither the school district nor the company that contracted to provide bus service has identified the driver. She is on leave during an investigation. Principal Cathy Lewis said she learned that the driver had been using duct tape for weeks on students, including two kindergartners. She said the driver denied it.
