Four students were arrested in separate drug-related incidents on a Deer Park campus.

The district said there were two cases, both at Deer Park High School-South Campus.

The school had received an anonymous tip that led to the arrests of three 10th graders and one 11th grader.

Deer Park ISD sent out a notice to parents which stated, "It is unfortunate that teens bring illegal drugs to school. But Deer Park Independent School District's response sends a clear message that such behavior will be punished to the extent of the law and school rules. Our highest priority is providing a safe learning environment for our students."
