Administrators have disciplined a junior Lawrence High student for putting a prescription medication into a teacher’s water bottle on Wednesday.

LHS Principal Steve Nilhas said students warned the teacher not to drink from the bottle, and administrators then began an investigation.

No one was injured in the incident, but administrators were able to identify the male student, Nilhas said.

Administrators then followed disciplinary procedures, including a suspension and notifying the student’s parents. The school also filed a police report in the case.

“The intent aside, we take things like this very seriously,” Nilhas said. “We have a certain obligation morally and legally to ensure a safe environment. The students understand that as well.”
