Mark Scherer: Sandringham Village general manager says the community looks to establish community patrols following road rage attack - Heather du Plessis-Allan Drive

Retailers in Sandringham are on the alert after more violence near their suburb last night.

A 15-year-old girl was seriously injured in a road rage attack, after offenders in a grey Mazda Axela hatchback shot three times into the minivan she was in.

Police say it started because the hatchback was "hard braking" in front of the van on the motorway.

Sandringham Village general manager Mark Scherer says they've been working on community patrols since superette worker Janak Patel was killed last year.

"Since then, we've been building multiple layers of security, primarily driven by the shopkeepers themselves."
