A mystery vandal who keyed the length of a stranger's car using an air hose at a petrol station is being hunted by police.
The incident was caught on CCTV at the South Hurstville BP in Sydney's south.
The woman, dressed in a bright green t-shirt and jeans, is seen approaching a blue sedan while holding an air pump.
She then keys the entire length of the right-hand side of the car before taking the pump over to her own car to fill one of the tyres with air.
The unsuspecting driver was inside the servo when the vandalism occurred.
NSW Police say they are confident they will identify the woman responsible.
The investigation continues.
