Police have arrested a 16-year-old who has allegedly been driving around Melbourne in a fake emergency vehicle.

It’s alleged the teen has responded to car crashes in the modified truck which appears to have flashing lights and sirens.

Michael Scanlan from Channel 7 was in Brighton when the teen was arrested and told Tom Elliott from the scene the car looked “incredibly real”.

“Someone had filmed it on their dascham and it had been posted on Facebook page,” he said.

Detectives from the Heavy Vehicle Crime Investigation Unit made enquiries into online footage that depicts a white truck travelling with what appears to be emergency lights flashing, through traffic.

A Brighton teen is assisting police with their enquiries.
