ALLEN, Kan. (AP) — An eastern Kansas school district has fired a bus driver following his arrest on suspicion of driving under the influence of alcohol.

KWCH-TV reports  the 57-year-old man was arrested Monday afternoon after pulling up to Northern Heights High School in Allen, about 20 miles north of Emporia.

An employee of the North Lyon County School District notified the sheriff’s office that a driver appeared to be driving under the influence. No students were on the bus.

The North Lyon County superintendent said the driver had worked for the district for eight years without any previous problems.

The sheriff’s office declined to comment about the driver’s blood-alcohol level. Charges were pending Tuesday.
