At least 25 people have been hit by crooks snatching bags from the front seat of their car in the past two months, police in Auckland say.
The thieves' modus operandi is to park behind a car, blocking it from reversing, before opening passenger doors and grabbing handbags from the front seat.
Most of the incidents have been reported in Counties Manukau, particularly Botany and Papatoetoe.
Police are warning people to lock the doors as soon as they get in their vehicle, in the face of the wave of robberies.
