A traffic controller was allegedly beaten up after telling two men he did not have time to give them a cigarette.
The two men started a conversation with the worker while their vehicle was stationary at the Springvale Rd roundabout.
The 60-year-old was stemming traffic congestion as resealing was carried out on London St when the assault occurred at about 5.30pm last Friday.
The worker asked the two men to move along so traffic could continue flowing, but they got out of their vehicle and attacked him using their fists and feet.
A witness to the incident who did not want to be named said two members of the public then got involved.
