Police are investigating an armed robbery of a woman at a milk bar in Dandenong earlier this month.
It is believed the woman was closing the Menzies Crescent store when was approached by a man just before 7.30pm on 20 August.
One of the men was carrying a small knife and grabbed the victim’s mobile phone.
The offender fled the scene on foot down Menzies Avenue towards O’Malley Crescent.
The victim chased the offender but was punched by a second offender who appeared from O’Malley Crescent.
Investigators have released a composite image of a man they believe may be able to assist with their enquiries regarding the robbery.
