A Massachusetts kindergartener can breathe easy. The 6-year-old no longer has to serve detention for bringing a plastic Lego-sized gun on his school bus, WGGB reports.

“He smiled when we told him, he was very excited when we told him he didn’t have to serve the detention,” Mieke Crane, the boy’s mother, said.

The incident took place on a school bus for Old Mill Pond Elementary School in Palmer, Mass., on Friday morning. Crane’s son brought a tiny toy gun – about the size of a quarter – on the bus. Another student noticed and yelled to the driver.

The school was notified, a letter was sent home to parents and the boy wrote an apology letter to the driver. Crane says she thinks the incident was blown out of proportion.

“I think they overreacted totally. I totally do,” Crane told WHDH. “I could see if it was you know, an air soft gun or some sort of pistol or live bullets or something. This is just a toy.” 

The school’s punishment was amended after the bus surveillance tape was studied. Crane met Tuesday with the principal, who said the boy would no longer serve the original punishment of a detention and a possible school bus suspension.

“She [the principal] looked at the tape, the children were not standing up hollering, nobody was ducking, no one was screaming he has a gun. The little boy raised his hand properly the first time,” Crane said.

This wasn’t Old Mill Pond Elementary School’s first incident with a child bringing a toy gun to school. In May 2011, a 9-year-old was summoned to juvenile court after brining an Airsoft gun on a school bus, The Republican reports.

But sometimes children bring the real thing onto school property. Recently a fourth-grader at Hamilton Elementary School in Sanford, Fla., reportedly brought an unloaded gun to school two days in a row before he was searched and the weapon found in his backpack, WFTV reports.

“That's bad,” Dennis Adono, a school parent, said. “It's getting to the point where, I mean, you hear that a lot now.  I don't know what's going on.”
