Mono Bar and Restaurant in The Arcadian Centre, Hurst Street
GANGS slashed each other with glass bottles, threatened ambulance paramedics and turned a hospital into a war zone in a mass brawl which broke out in a city bar.
The nightspot hit by one of the worst outbreaks of violence "ever seen" by police has had its licence immediately suspended.
Officers used batons, CS gas and brought in dogs after a fight inside the Arcadian's Mono Bar in the early hours of Sunday morning.
Police say customers used CS gas inside the premises in a massive fight that soon spilled into the street where glasses and bottles were used as weapons
A number of people were treated at hospital for nasty slash and stab injuries after the 3.30am fight, including one man who may now lose the sight in one eye.
Ambulance staff were threatened whilst treating victims and police had to be deployed to City Hospital where the injured men continued to clash.
Licencing chiefs suspended the bar's licence in an expedited review on Friday, ahead of a full hearing in a month's time.
Police applied for the immediate suspension and full licence review after no call was made to them about the disorder from the premises.
Officers rushed to the scene after being alerted to the brawl by CCTV operators and had themselves used CS Spray within two minutes of arriving.
A report to the Licencing Committee, from Superintendent Andrew Beard, said officers had also pressed emergency buttons requesting as much backup as possible.
The report added: "What the officers faced has been described as some of the worst disorder they have ever seen.
"They have described a large-scale violent fight. Officers believe CS Gas may have been discharged inside the venue during the initial disorder by customers.
"Officers had to use dedicated public order tactics to disperse the crowd, use CS spray and draw batons."
The streets around the Arcadian Centre were turned into a battleground by the yobs, police said.
The report added: "The incident continued around the Arcadian Centre and the adjoining streets. This has included males exiting vehicles and fighting, as well as males carrying and using weapons.
"Due to the intensity of the disorder, further resources were deployed, including dog units. Police also assisted ambulance staff with injured persons as these were being violent and aggressive to ambulance staff.
"One male was escorted to hospital and it is possible he could lose the sight in one eye.
"Males involved in the disorder presented themselves at City Hospital. The friction between two specific groups continued at the hospital and further police resources were requested.
"Officers have described the incident as amongst the worse disorder that they have witnessed within the night time economy."
This isn't the first time the venue has been hit by extreme violence.
Last year the Birmingham Mail revealed how officers came under fire from a gang of nightclub yobs who pelted them with glass and champagne bottles.
Police arriving at the scene found thugs fighting with bar staff and others exchanging blows in the club's smoking area.
But when officers tried to diffuse the situation between the two groups they were greeted with a hail of missiles, including a large champagne bottle.
West Midlands Police issued CCTV images from club cameras of the disorder on Saturday April 27.
