The mother of a man stabbed to death in Oceana says she will sue the club over “negligent door staff”.

The Kingston nightclub’s licence was withdrawn by a council committee on Tuesday throwing its future into doubt, but the venue will stay open pending an appeal.

A security “loophole” through the Woo Woo bar, which does not have metal detectors, is believed by Oceana to have allowed a knife to be brought into the club the night 20-year-old Jamie Sanderson was killed.

They also heard a “culture of criminality” had led to more crimes than any other London club in the past two years. The club is one of the largest in the country.

Carol Sanderson, 48, who worked in nightclubs for more than 11 years, said club owner Luminar had not contacted her to offer condolences.

She said: “Where were the people watching the CCTV? Where was the security when my son was being attacked? Why did no one from the club step in? How did they get the knife past security in the first place?

“It is a joke. My son would still be alive if they had done their jobs properly.

“There has been so much negligence by this club. One manager will step down and nothing will change. I doubt they will even change the security company.

“Security has been exposed, but still they want to open their club to make money. It is disrespectful to me and to my son’s memory for them to re-open so soon.

“The kids should boycott the club because they are obviously not safe in there.”

She now plans to lead a march against knife crime from Oxbridge Road in Southall to Ealing Common, starting at noon on Sunday.

She said: “There are people who want to retaliate for what happened to my son but I am telling people this madness must stop. No more fighting, not over my son, not over anything. It has to stop.”

An Oceana spokeswoman said: “The death of Ms Sanderson’s son was a tragedy and we offer our deepest condolences for her loss."

She said the club had more than 100 CCTV cameras and due to the sophisticated security systems in place had been able to help with the police investigation.
