Police are appealing for public assistance following an armed robbery on a security van in Mulgrave this morning, Victoria Police say.

The circumstances surrounding the incident are yet to be established but at this stage it is believed a motorcyclist armed with a firearm held up the van at a shopping centre on Jacksons and Police roads shortly before 8.30am.

No one was injured during the incident, however a quantity of cash was taken.

Investigators have been told the man was wearing a blue top and black helmet and fled on a motorbike, which wasn’t bearing plates.

It was last seen heading eastbound on Jacksons Road.

Police believe the bike may have been spotted in the Noble Park area shortly after and are keen to speak to the person who reported it to Triple Zero.

Anyone who sights the bike or has information is urged not to approach the man but to instead call Triple Zero (000) immediately.
