Police are appealing for public assistance following an armed robbery in Morwell last weekend.

Investigators have been told a man armed with a handgun entered a fast food restaurant on Princes Drive and demanded money from the tills about 12.10am on Saturday 2 June.

The victim, a 26-year-old woman from Morwell, handed over a sum of cash and the offender fled the scene on foot.

The offender, who covered his face with ski googles and a scarf, was last seen heading north on Princes Drive.

The man, who was also wearing a black hooded jumper with yellow trim around the hood, is perceived to be of Caucasian appearance and about 170-180cm with a thin build.

Detectives have released images of a man who they believe may be able to assist with their enquiries.
