The Butler School District has removed a Valley Lines bus driver this week after an internal investigation.

On Tuesday night, according to a statement Wednesday made by the district, “a concern regarding Middle School transportation was reported” to the district.

The district launched an investigation, which revealed that a bus driver acted in a manner that was “not in accordance with the standards held by the Butler Area School District,” according to the statement.

As a result, the district requested that Valley Lines remove the driver from all Butler bus routes.

No other information about the driver's conduct or the district's investigation was immediately available.
