Dandenong police are appealing for witnesses following a series of what are believed to be deliberate collisions in the Springvale area last week.
Investigators have been told a black Volkswagen hatchback was seen traveling at a fast rate of speed following a purple Mazda 3 about 11.50am on Thursday 15 October.
It is believed the Volkswagen swerved in front of the Mazda and struck the side of it multiple times on Police Road, Springvale Road, and Glenvale Crescent.
Investigators are appealing for anyone who witnessed the incidents, or who may have dash-cam footage of the cars to contact police.
Police believe both drivers are known to each other and no injuries have been reported as a result of the incident.
Anyone with information is urged to call Crime Stoppers on 1800 333 000 or log onto www.crimestoppersvic.com.au.
