A reveller seen dancing alone at a busy nightclub allegedly unleashed a barrage of punches at fellow partygoers just seconds later.
The incident was captured on camera at Canberra's Mooseheads nightclub back in January, but police have renewed calls for witnesses to come forward.
CCTV footage shows the alleged attacker dancing by himself at the bar shortly before a wild brawl broke out.
Several punches appeared to be thrown, before the altercation came to abrupt end when other patrons and staff members stepped in.
It is not clear from the CCTV footage whether anything was said to provoke the alleged attack.
Police want to speak with the man over the alleged assault, but it was his dance moves prior to the brawl which sent social media into a spin.
'Hope he gets extra time for that dancing,' one wrote, while another said: 'The real crime here is his dance moves.'
'Poor guy was having a seizure and everyone thinks he was dancing,' yet another commented.
ACT Police is urging anyone who witnessed the alleged assault, which left one man with facial injuries, to come forward.
'Police are urging anyone who recognises themselves in this footage from an assault at Mooseheads nightclub on Sunday 8 January to come forward and speak to police,' a statement read.
'The assault occurred around 4.10am and involved a number of people, resulting in a male victim suffering facial injuries.'
The alleged attacker was wearing a long sleeved shirt, dark pants and white shoes.
