A Concord High School math teacher was arrested on Wednesday in a school parking lot.

It happened in the Concord Junior High School parking lot.

Anna Kridler is charged with Operating a Vehicle While Intoxicated – Endangering a Person after witnesses told the Concord School Resource Officer they saw Kridler driving the vehicle.

Reports say she smelled of alcohol and had poor balance.

Kridler refused a chemical test, but a warrant was obtained and a blood draw was done that evening. Results are pending, and her first hearing is set for May 23.
