Fawkner Embona is appealing for information following an armed robbery in Coburg on Sunday.
Investigators have been told a man entered a Sydney Road liquor store, armed with what was believed to be a syringe, about 2.45pm.
The attendant was threatened before handing over an amount of cash to the offender who fled the store on foot.
The wanted man is perceived to be Caucasian in appearance, with a thin to medium build, believed aged in his 30s and spoke with an Australian accent.
He was wearing a light coloured baseball cap, black hooded jumper with a ‘Lonsdale’ logo, jeans and white and black runners.
Police have released images of a man they believe can assist with their enquiries.
