Students in the Keller Independent School District are banned from bringing backpacks, athletic bags and duffel bags to school this week.
The move is part of the district’s plan to keep students from carrying out end-of-the-year pranks.
Students turned in their textbooks and will not be allowed to stop at their lockers this week, the final week of school before the semester ends on June 5.
The district has seen trouble with pranks in the past.
Two weeks ago, school leaders said someone broke into Timber Creek High School and started dumping items into the classrooms and hallways.
The administration sent a letter home to parents that said this is no longer a prank, but a crime.
In 2012, students poured baby oil and other liquid on the hallways floors. They also released crickets, birds and rats into the school.
