Police are investigating after a man was stabbed with a pencil in a Melbourne laneway last month.
Investigators have been told the male victim was standing in the laneway smoking while on a work break about 2.30pm on 17 March.
An unknown man approached the victim, dragged him to the ground and stabbed him multiple times with two pencils.
A number of witnesses attempted to push the man off the victim but he continued the attack before walking away towards Collins Street.
The victim, a 20-year-old South Yarra man, was taken to hospital with minor injuries.
Investigators have released CCTV of a man who they believe may be able to assist with their enquiries.
Police are urging anyone who can identify the man or with information to contact Crime Stoppers on 1800 333 000 or submit a confidential crime report at www.crimestoppersvic.com.au
