Banyule-Nillumbik Crime Investigation Unit detectives continue to investigate an arson and criminal damage incident at a business in Greensborough on Saturday 5 July.
It is understood five unknown people attended the business on Para Road about 3.55am.
The offenders gained entry to the business before setting fire to three cars.
The group also used red spray paint to write various slogans on the cars and on a building wall.
One of the vehicles was destroyed, while the other two sustained moderate damage.
Detectives believe the group left the business via a back fence and were last seen travelling in a south-westerly direction along Plenty River on e-bikes.
Detectives are today releasing CCTV of five people they would like to speak to in relation to the incident. Each person was dressed in black hooded jumpers, backpacks and gloves.
Local detectives are investigating the incident, with the support of specialists from Crime Command Arson and Explosives Squad.
While investigators continue to liaise with Counter Terrorism Command to establish if there are any connections to the arson on the synagogue in East Melbourne and a public order incident on Hardware Lane; at this time no links have been identified.
There is absolutely no place at all in our society for antisemitic behaviour.
Anyone who witnessed the incident or has information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au.
