(VALPARAISO) - A Morgan Township High School student faces expulsion after a shotgun, 140 rounds of ammunition and other weaponry were found in his trunk.

18-year-old Ryan Gaddis was charged with possession of a weapon on school property and is being held in Porter County Jail.

Gaddis admitted to having the weapon in his trunk, but later told police he meant to leave the weapons at a relative's home before coming to school. Gaddis was arrested without incident and taken to the jail.

Under Indiana law, a student in possession of any type of firearm on school property must be expelled for at least one calendar year.
