Police are investigating after a video was posted online which appears to show someone throwing a traffic sign onto a highway in Oakville, Ontario, while cars were rushing by.
The video shows a young man tossing a street sign from the Winston Churchill Boulevard overpass—a la “chair girl”—onto the Queen Elizabeth Way.
“The sign was thrown down onto the live, eastbound lanes of the highway,” said investigators with Halton Regional Police Service.
Police say they do not know when the incident occurred.
“The behaviour depicted in this video is extremely dangerous and criminal in nature.”
Images on Google Maps from Winston Churchill Boulevard show a “right lane exit” sign, which bears a striking resemblance to the one being thrown in the video.
Video from the CTV Toronto News chopper captured on Friday morning showed that the sign was missing.
Police say they’re “committed to identifying the person responsible.”
