Police are still calling for public assistance to help solve an armed robbery which occurred at a supermarket and bakery in Port Melbourne.
The incident occurred on 18 June around 10.25am and involved a group of five men entering a shopping centre, threatening staff with knives and cleavers and stealing cash.
Detectives have worked around the clock and have recovered a stolen Holden Commodore that they believe was used in the robbery.
It was recovered in Newport on 21 June.
Investigators have also recovered knives and cleavers that may have also been used in the robbery.
These items were allegedly dumped in grassland in Wyndham Vale after the Saturday morning robbery.
Police now believe that the same offenders are responsible for two similar robberies that were committed within 20 minutes of each other in Maribyrnong and Newport.
Supermarkets in Wests Street Maribyrnong and one in Mason Street Newport were robbed on 21 June between 12.30 and 12.50pm.
Police have released photographs and CCTV of individuals that they believe may be able to assist with their investigation.
