QUEEN CREEK, Ariz. (3TV/CBS 5) – A Queen Creek school has placed its principal on administrative leave after a Grade 4 student brought a gun to school on Thursday.

Legacy Traditional School officials released the following statement regarding Principal Megan Alvarado:

“The well-being of Legacy students, faculty, and staff is our top priority, and that includes supporting a safe, inclusive, and welcoming learning environment. We are investigating the circumstances surrounding Thursday’s discovery of an armed student on campus, and that investigation includes verifying that the administration has always followed Legacy security protocols.

We look forward to continued conversations with our students, parents, teachers and staff to ensure our school lives up to Legacy’s high standards.

On Wednesday, a student told his parents he saw something suspicious at school. The child’s parents informed school officials and the next morning a fourth-grade student brought a gun into the school in his backpack. According to Queen Creek Police, staff called the police and took the child away from other students. Legacy Traditional School says the student never took the gun out of his backpack.

On Thursday, school officials said they were cooperating with police during their investigation.
