A student brought a gun to a northwest Orange County high school Tuesday, forcing officials to put the school on lockdown so they could search for it.

Officials at Wekiva High School say they were notified about the gun around 2:30 p.m.

They say another student learned that a fellow student was hiding a gun in their backpack and reported it. 

The school was immediately placed on lockdown as deputies searched the grounds.

They located the gun and arrested a 17-year-old student.

The lockdown ended about an hour later.

Some parents are upset however, saying they did not get the call alerting them of a safety concern until after the lockdown was over.

"We should've been informed as soon as the situation transpired," said parent Melody Davis.

The school's principal sent out the audio message after the lockdown was lifted. In it, she says the weapon was never used in a threatening manner.

All after-school activities were canceled for the day.
