A Brenham teen is facing assault charges after police say he punched a high school teacher Thursday.
According to authorities, the instructor told the 15-year-old boy to tuck in his shirt, per school regulations.
After yelling profanities, police said the student punched the teacher in the arm and then slapped her hand.
The boy was arrested for disorderly conduct, but a charge of assault on a public servant is pending, Brenham police said.
The teacher was treated by the school nurse and was back at work the next day, according to Brenham ISD officials.
