This is the shocking moment a brawl erupted in a bar as boozers smashed chairs over each other and used glasses as weapons.
Footage shows around 20 men punching and kicking each other as helpless bar staff watch on.
One doorman attempts to break the brawl up but the fight carries on as brawlers hurl chairs across the room.
The fracas broke out in The Arc Bar in Leeds, England, in the early hours of Saturday. Leeds is a large city 200 miles North of London.
Cops were eventually called to break up the clash, which left a 28-year-old man needing hospital treatment for a head wound.
A 21-year-old man was later arrested on suspicion of violent disorder and has been released under investigation.
Police are now appealing for information to identify the brawlers.
Detective Inspector James Entwistle, of Leeds District CID, said: “The situation appears to have started with a confrontation between two people that has then quickly turned in to a mass brawl.”
“These were some very ugly scenes where people were punched, kicked and stamped on and glasses and chairs were thrown.”
“The video shows how there was very little that the bar’s security could do to control the situation and it was clearly a shocking thing for staff and other people in the bar to witness.”
“We are treating this as an incident of violent disorder and are carrying out inquiries to identify those involved.”
“We do have very clear CCTV footage that captures the whole incident and are working through that in detail to identify the main suspects.”
“We would like to hear from anyone who knows the identity of any of those shown fighting in the clip we have released or who recognizes themselves as a witness.”
