Fire fighters were first called to a car fire on near the intersection of Miles Street and Grant Street in Sebastopol following reports a car had been dumped in a paddock and torched.

The fire was eventually brought under control with no harm coming to any surrounding properties.

A Ballarat City Fire Brigade spokesman said the car was without number plates and the incident was now a police matter.

Following this a second car was ignited at the BP Petrol Station along the Western Freeway at Warrenheip around 4.15am on Wednesday morning.

Firefighters were initially told the blaze was burning close to the petrol bowsers, however on arrival it was thankfully some distance away in a car park.

These are the 21^st and 22^nd deliberately lit car fires The Courier has reported on across the first 72 days of 2019.

Detective Senior Sergeant Tim Argall says the frequency of the blazes are a major worry for police.

"It's a big concern," he said.

Police are urging anyone with information regarding either of these incidents to submit an anonymous report to Crimestoppers on 1800 333 000 or online at www.crimestoppersvic.com.au.
