A group of five men were allegedly involved in the assault of two others at Kingston Foreshore last month.
Police have released a photo captured by one of the victims in the hope of hunting down the alleged perpetrators.
Police allege two men were assaulted and their vehicles damaged on Eastlake Parade about 11.30pm on November 19.
Officers have already spoken to some witnesses but are aware there are more people who were in the area at the time who are yet to contact police.
Detective Inspector Adrian Craft said police wouldn't tolerate anti-social behaviour and had ramped up patrols at popular night spots in preparation for summer.
"No one deserves to be assaulted on a night out," he said.
"Know your limits, drink responsibly and lookout for your fellow Canberrans."
