St Kilda Crime Investigation Unit detectives have released a FACE image of a man they would like to speak to following an armed robbery at a milk bar in Elwood.

Investigators have been told two men attended the Dickens Street milk bar around 8.50pm on Tuesday 17 February.

Once inside, one of the men menaced a female staff member with a small knife and made demands for cash while the other man acted as a look out at the front of the premises.

The staff member complied and handed over an amount of cash. The pair then fled the scene in an unknown direction.

Police have released the below image of a man they believe may be able to assist with their investigation.
