RICHARDSON, Texas (AP) — A substitute teacher suspected of being drunk in a suburban Dallas middle school class was too intoxicated to complete a sobriety test and was arrested, authorities said.

Thomas Brownlee, 56, was in a classroom Tuesday with students and another staff member for about 20 minutes, Richardson School District spokesman Tim Clark said. Another teacher suspected Brownlee was drunk and told a police officer.

A Dallas police report states that Brownlee "had slurred speech, breath smelling of an alcoholic beverage and bloodshot eyes."
