A men’s bathroom toilet in a convenience store bathroom was found destroyed after store employees heard a loud bang, according to Madison police.

Officers were called to Kelly Williamson Mobil at 901 S. Gammon Rd. at 4:44 p.m. Thursday when employees discovered the shattered toilet.

Employees didn’t realize the bang was from inside the building and found the broken toilet after a customer left a note indicating the toilet was in need of repair.

Police said bullet fragments and a shell casing were recovered from the scene.
