A Whites Creek High School senior was charged Friday after police found a gun and ammunition on school property.

Michaiah Nelson, 18, was charged with unlawful weapon possession and carrying a weapon on school property.

Another student tipped off school officials that Nelson was allegedly carrying a gun in his waistband. They searched a bathroom, where a weapon was found hidden behind a ceiling tile.

During the search, Metro Nashville police reported Nelson said, "You all must have found my gun."

The gun in question was a .380 caliber pistol with 10 rounds in the clip but nothing in the chamber.

Nelson remained in custody Friday afternoon in lieu of a $1,500 bond.
