“From the New Zealand Police –

You get in your car/suv and notice a piece of paper stuck to your  back window.

A new hijack trick.

You get out of the car – motor running – walk around to the back of the car, and a sneaky hi-jacker climbs in, and drives off – probably with your handbag/phone etc.

Lesson – leave the offending piece of paper, and drive off – sort it out later.”
