Armed Crime Squad detectives are appealing for public assistance following the investigation into an armed robbery at a Newcomb hotel on 25 February.
Detectives have been told a man entered the hotel situated on the Bellarine Highway about 2.30am.
It is believed the man, armed with a sawn-off shot gun, approached the cashier booth and made a demand for cash.
The offender stole a large quantity of cash before leaving the store via the front door.
It is believed the offender fled the scene in a small light coloured sedan or hatchback.
The offender was wearing a white balaclava, black gloves, grey hoody, dark jeans and black and white runners which had pink laces on the left shoe.
Detectives have released images and CCTV of a man who they believe may be able to assist with their enquiries.

Investigators believe the offender was involved in a collision with an unknown person in the Newcomb or Whittington areas following the armed robbery.
Details were exchanged and detectives are keen to speak to that driver.
