(GunAuction.com) — A Canadian father was arrested and strip-searched recently after his 4-year-old daughter drew a picture of a gun in her kindergarten class, two Canadian newspapers have reported.

Ontario dad Jesse Sansone told the Toronto Sun his little girl’s drawing was supposed to be him, getting monsters and bad guys. Her teacher apparently thought differently, and the school contacted child protective services. When Sansone arrived to pick his daughter up, three police officers were waiting to take him into custody.

“I’m picking up my kids and then, next thing you know, I’m locked up,” he told the Waterloo Region Record. “I was in shock.”

Police questioned Sansone’s daughter and his other children, who gave a “detailed description” of a firearm supposedly located in the house and easily accessible to them, Inspector Kevin Thaler of the Waterloo Regional Police said, according to the Calgary Herald.

The “gun” his children told police about? A toy pistol that shoots foam darts, which police discovered during a search of his house.
