A Southbridge, Massachusetts, school teacher allegedly planted live ammunition at his school then called 911 to report having found the ammo.

According to WCVB, 57-year-old  Alfred Purcell, reported finding “9 mm ammunition in the rear stairwell” of Southbridge High School. His report led to a lockdown, during which the police examined surveillance footage and saw Purcell allegedly taken ammo out of his own pocket, “dropping it on the floor and quickly leaving the area.”

ABC News reports that Purcell was arrested and police found over 100 live rounds in car. He allegedly told officer he planted the ammo to “prove to the school that they needed to get metal detectors.”

Southbridge Police Chief Shane Woodson saying, “There was no kids that were injured, nobody was seriously impacted by this other than we went into a lockdown for an hour and we had to investigate a teacher who was doing things he shouldn’t be doing,”

Southbridge superintendent Jeffrey Villar said, “This individual acted in a disgusting manner. I feel very badly for our students because it is an adult who failed them.”
