Police investigating a shooting in the wake of a mass exodus from a nightclub foam party have reiterated their witness appeal.

Officers discovered a 22-year-old with a gunshot wound to his knee in Abbey Road at 3.10am on Sunday June 29, and found a second man, also 22, suffering head injuries, who not been shot .

The attacks occurred after revellers fled from  a £15-a-night called UK Foam Party celebrating its fifth anniversary at The Lounge nightclub at Unimix House in Abbey Road, Park Royal.

Promoters of the night, which boasts the largest foam machine in the UK, later criticised on Facebook the "imbeciles" who had spoiled the evening.

They said: "A tear gas-like substance was let off on three occasions in the venue by a couple of individuals who we would love to identify and [who] barged their way out like they were victims.

“We would like to understand why you came to sabotage UK Foam Party.

“It was well orchestrated by the individuals that used the tear gas when the CO2 machine was activated.

“There was a fight outside the club and someone has been wounded in the leg.

“Luckily [there was] no loss of life in the rush and panic to escape the harmful fumes in the club.

"The promoter had not been aware of any breach of the building until the gas was let off on the security, but was not totally happy with the arrangement of the venue."

The Metropolitan Police said in a statement: "Neither men's injuries were life threatening and they have since been discharged from hospital and recovering at home.

"Both men had attended a foam party at the club.

"There have been no arrests at present and enquiries continue."

The licence of The Lounge was suspended on July 3, just a few days after the shooting, by Brent Council and the police applied for a review of the club's licence , which was carried out yesterday by Brent Council's alcohol and entertainment licensing sub-committee.
