Liam Turbett, 23, John Bennett, 37, James
Nesbitt, 26, Dominic
McGoldrick, 19, and
Matthew Crerar, 27, were involved in the chaos.
Taxpayers had to stump up almost £24,000 to clean up the mess
party goers left behind.
The bash, in Kelvingrove Park in April 2011, attracted almost 6000
people after it was
advertised on social media.
The mood turned
violent around 5pm when music sound systems were switch off.
Turbett, from Maryhill, admitted being part of a disorderly crowd
and escaping from
lawful custody after struggling violently with police.
Bennett, from Drumchapel, and McGoldrick, from Darnley pled guilty to being part of a group that struggled with police and freed Turbett.
Crerar, from Partick, admitted freeing Turbett from police custody. James Nesbitt pleaded guilty to carrying out the police assaults.
CCTV footage of the incident which was filmed from a police helicopter was shown to the court.
Procurator fiscal depute Richard Hannay said there was no permission granted by Glasgow City Council for the event.
Turbett being held by two officers when they
were surrounded by a mob, including Bennett,
Crerar and McGoldrick, who helped free him.
Turbett, a history graduate from Glasgow University, was previously involved in the Free
Hetherington occupation in August 2011.
This was a campaign to prevent the closure of a post graduate club at the university.
The men will all be sentenced next month at Glasgow Sheriff Court – more than two and a half years after the party.
