New York, Feb 14 (IANS): A school bus driver was removed from her route after she took a selfie showing her taking a swig from a bottle of beer behind the wheel.

First Student Bus Company, which operates in Princeton, Ohio, removed the driver from her route pending an internal investigation, WXIX reported.

The company said the photo was taken at the end of her route when there were no children onboard, and that the bottle was not open.

Still, the behaviour was completely unacceptable, they said.

"We are incredibly disappointed by our driver's actions," the company said in a statement.

The driver, whose name has not been released, shared the photo online.

Princeton School District authorities said they were investigating the incident with the bus company.

"Our main concern is the safety and security of our students," said Ed Theroux, district superintendent, in a statement to the Cincinnati Enquirer.

Parents said the woman should not be allowed to drive buses for the district again.
