Mystery surrounds car hanging from bridge by a wire

Authorities and onlookers have been left baffled by a car hanging from a wire off a bridge.

Police were called to Leaside Bridge in Toronto, Canada, on Wednesday to find the bizarre sight.

Photos taken by bystanders show the Honda Civic dangling vertically with a wire appearing to be attached to the front bumper.

Motorists were travelling across the busy bridge without realising what was happening underneath.

Toronto Police initially thought the car could be part of a movie set, but later tweeted there was no film shooting authorised.

“[The] reason is still unknown,” they said.

Many have speculated on social media, suggesting it could be an art installation, a prank or even aliens.
