A 15-year-old boy has been charged with mischief after he allegedly packed a bomb-shaped alarm clock in his carry-on luggage that caused a temporary shutdown at one of Pearson International Airport’s security screening areas Saturday afternoon.

According to Peel police Const. George Tudos, the teen, on his way to Vancouver, was passing through a security screening area in Terminal 3 when an x-ray machine detected what appeared to be a device with wires taped to several sticks of dynamite in his carry-on bag. Airport staff shut down the area and called Peel police, who sent their Explosive Disposal Unit to the scene.

After two hours of investigation, the unit determined that the item was, in fact, an alarm clock, and the security area was reopened.

The 15-year-old, who cannot be named under the Youth Criminal Justice Act, has been charged with mischief and will be appearing in court in October.

Tudos could not comment on the teen’s motive but said that alarm clocks identical to the one the teen had in his bag are readily available on eBay.

American company Nootropic Design sells what appears to be an identical clock and posted a disclaimer on its website.

“Dear Pranksters:

Yeah, you. I know you are excited to scare your friends and coworkers with a phony bomb, but use your head. This kind of device can make people freak out and call the authorities. So don't bring this to school or to work, and certainly don't bring it anywhere near an airport! Seriously, don't get yourself into trouble.”
