Recently released CCTV footage has shown the aggressive moments that led to former North Melbourne captain Jack Ziebell being assaulted outside a South Yarra venue late last August.

However, an attacker at the centre of the fray has narrowly avoided jail time, instead receiving fines and a stern warning from the magistrate.

Ziebell and his now ex-teammates had gathered at The Osborne on Commercial Road on the evening of Saturday, August 19 to celebrate the now-retired Roo's career with the club.

The 32-year-old was eventually set upon by a group of men, identified as Ibrahim Behluli, 21 years of age, Abdul Karim, 29, and Masihullah Rawani, 27, with Ziebell requiring facial reconstructive surgery due to the array of injuries sustained.

As exhibited by Nine News, closed circuit television footage shows Mr. Rawani also set upon fellow Kangaroos Curtis Taylor and Charlie Comben within the confines of the rooftop bar venue.

Mr. Rawani appeared before Magistrate David Starvaggi on Wednesday, receiving an $1800 fine and the following warning:

"This is behaviour of the worst kind," Starvaggi expressed.

"Your conduct is intolerable.

"Don't ever get involved in anything like this ever again."

Rawani's accomplice, Mr. Behuli - the man accused of attacking Ziebell - was charged with intentionally causing injury and committing affray by using unlawful violence.

Mr. Behuli will return to the Magistrates Court at a date set for next week.

Ziebell played 280 games for North Melbourne between 2009 and 2023, leading the club for six seasons from 2017 to 2022.
