Kingston Crime Investigation Unit detectives are investigating a robbery and assault in Dingley Village last month.
An 18-year-old male was on a Dandenong bound bus from Mentone Railway Station on 9 October about 4.50pm.
The teenager got off the bus on Centre Dandenong Road about 5.20pm and was followed by an unknown male to Lee Andy Court.
The offender demanded the victim’s shoes then hit him multiple times causing him to fall to the ground.
The teenager’s shoes were then forcibly removed, and the offender fled on foot.
The offender is perceived to be of Islander appearance with distinctive long ‘boofy’ curly hair, aged in his late teens with a solid build, wearing glasses and carrying a blue Adidas bag with white stripes.
It is believed this man boarded the bus on Chapel Road near Herne Close in Moorabbin about 4.25pm.
Investigators have released CCTV and still images of a male they believe may be able to assist with their enquiries.
Investigators are urging anyone with information or who witnessed the incident to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au
