Three Houston high school teachers were arrested on drug charges today.
The arrests came after officials at Yates High School ordered a search of employee and student parking lots on the south Houston campus. Two teachers were charged with possession of marijuana, while a third was arrested on suspicion of illegally possessing prescription drugs.
The arrests are the latest in a string of cases involving Houston school district employees caught with illegal drugs. At least 12 Houston district employees have been arrested on drug charges. The Houston Chronicle reports that's prompted Superintendent Abelardo Saavedra to consider more random drug-dog searches and other strategies to combat the problem.
The Houston school district has about 30,000 employees.
