Body cameras and fog cannons have been introduced to Woolworths stores as part of new security measures. 

The supermarket giant is reporting a 131% rise in physical assaults on staff in the past six months, compared to the same time last year. 

Fog cannons have been rolled out in stores which have seen multiple break ins, while body cameras are being trialled in ten stores. 

Spokesperson Denva Wren told Mike Hosking that they're used as a deterrent and have so far been used for minor events. 

However, she says, they're seeing behavioural changes from aggressive customers when they have been activated.
