BRIDGEPORT TWP, MI -- A student is in juvenile detention after being caught with a loaded gun on school grounds.

Staff at Bridgeport-Spaulding High School was alerted by the parent of another student who said they believed a student had a gun, according to Superintendent Carol Selby.

The high school was placed in secure mode and the student was brought out of class where officials searched the student's backpack and found a loaded gun, Selby said.

Selby said the situation was contained to within 15 minutes and the student was very cooperative.

"There was no indication he was planning to shoot up the building," Selby said.

The student told school officials he needed the gun for protection but did not say from who or what.

Parents have been notified about the incident, Selby said.
