A Marana High School student was arrested Thursday after officials say he took a gun to campus.
A student told administrators Thursday morning that another student was armed with a handgun, a Facebook post from the Marana Police Department said.
The school resource officer found the student, detained him and found a gun, officials say.
Police said the student was then arrested.
All students and staff at the school were safe and the campus was secure, the Facebook posting said.
