Horrifying CCTV shows Douglas throwing the first punch before others rush to get involved.

Six people can then race up the stairs armed with bottles of champagne, sparking a mass brawl in the lounge area of the nightclub.

One clubber can be seen viciously smashing another over the head with a bottle as the brawl escalates.

Outnumbered police arrived at Projekt nightclub to find Douglas and others had been stabbed.

He was rushed to Bristol Royal Infirmary, which was placed on lockdown by police, with armed response cars on guard over concerns of a second wave of violence.

Douglas, of Horfield and Powell, of Totterdown, Bristol, pleaded guilty to affray at Bristol Crown Court on Thursday.

Gregory Gordon, prosecuting, described how the venue in the city centre held a ticket-only R'n'B on the evening of Boxing Day 2015.

Mr Gordon said: 'The first punch is thrown by Douglas at Powell before Powell leaves.

'Then six people come up the stairs, with Powell at the front, and there are punches between Powell and Douglas, and champagne bottles are thrown.

'Things then escalate into a lounge where there is a single, continuous brawl which snowballs out at the event.'

He added: 'A number of people were stabbed and some appear to be fully involved themselves.

'Police attended what they described as 'carnage' with 100 people in the street, some still fighting.

'Police were outnumbered and people simply walked away. 'Two people with knife wounds were taken to hospital.

'Bristol Royal Infirmary was put in lockdown overnight until 7am, enforced by three armed response vehicles.'

Kannan Siva, defending Douglas, said the catalyst for the incident was 'words exchanged' between clubgoers.

He told the court: 'There's no doubt my client's foolish actions instigated this disorder.

'He is then the recipient of group hostility. It ended with him receiving the most serious injury of the evening.

'It was like he was at the mercy of a pack of animals.'

Tabitha Macfarlane, defending Powell, said: 'He is very disappointed with his behaviour. He feels he's let himself down.'

Judge James Patrick jailed Powell for ten months and Douglas for nine months.

He told them: 'Your behaviour led to a shocking piece of violence in a club.

'Dozens of people would have had their time ruined. A number of people were slashed or stabbed.'
