Investigators have also released CCTV images of two men they would like to identify and talk to in connection with the incident, which occurred on Friday, 2 April 2010.
Detective Constable Jason Ridgeway, the investigating officer, said the incident took place around 11pm after a group of men had been to the club to watch the band ‘Sound of Sirens’:
“As the band finished, the victim, a member of security staff, approached a group of four men and informed them that the two who were aged under 18 years would need to leave.
“In doing so, the other two men began to get angry and refused to leave the premises.
“An altercation took place resulting in the victim, a 44-year-old man from Leeds, being headbutted, pushed to the floor and hit about the head with a bottle.
“As the fight worsened, one of the men, along with the victim, fell down the stairs leading to the exit.
“As the victim was on the stairs, he was subjected to more physical abuse when one of the men stamped on his leg which left him with a serious fracture to his tibia.”
Shortly after, other members of security staff arrived and removed all four men from the premises.
DC Ridgeway added: “This was an unnecessary and violent attack which left a member of staff with serious injuries.
“We have isolated images of the two men we wish to identify, and I would urge anyone who recognises them to come forward.”
