Police in Holland have warned Smart car drivers there is a growing craze where people are tipping their tiny cars into canals.

In Amsterdam, several Smart cars have already been tipped into canals after parking next to them, in the craze dubbed ‘Smart tossing’.

It is thought that Smart cars are being targeted because they are small enough to be parked facing the water, as opposed to being parallel to it.

As a result, groups of youths who have just the right level of alcohol and cannabis in their body, have an uncontrollable urge to 'toss' the car into the water.
