A millionaire former Big Brother housemate filming a gangster movie sparked an armed police response after two fake guns were allegedly discovered in the boot of his Bentley.

Nightclub owner Chelsea Singh, a contestant on last year’s series of the reality show, was dining with director Wayne Moseley after a day on set when armed police stormed the restaurant in Old Kent Road.

The pair had allegedly been spotted outside Rock Island placing two guns, used as props, in the boot of Mr Singh’s black Bentley convertible, leading a member of the public to dial 999.

The two men explained the replica firearms - an Uzi and a handgun - had been used earlier in the day while filming Mr Singh’s cameo in British gangster flick “Little Bastards”.

The director, whose works under the name “Yuppie Wayne”, said: “We took a couple of shots with the guns in Camberwell, and then went to have dinner down Old Kent Road.

"We put the guns in the boot, rather than leave them on the seat of the car.

“We’d just finished our meal and they rushed through with guns.”

Pictures from the raid on Thursday show at least six officers, some carrying machine guns, surround the pair inside the restaurant.

They were taken to Walworth police station where they were both charged with possession of an imitation firearm.

Both have been bailed and are due to appear in court later this month.

The director, 45, said the guns were an Uzi-style BB gun and a silver handgun.

He added: “We had a convertible Bentley outside and the guns were in the boot. We couldn’t shoot up the restaurant – the guns were in the car, so that doesn’t make sense.

“Nobody’s had that reaction before. I’ve had film sets where there have been 20 guns, and police turn up and just say: ‘What are you filming?’”

Mr Moseley said officers had confiscated his camera equipment, adding: “They did me over. They put me out of work.

“I run youth projects with kids, I’m not the guy they’re trying to portray me as.”

The incident took place at Rock Island, a Cypriot restaurant which opened last year on the site of historic pub the Thomas A Beckett.

Mr Singh, 49, was the fifth contestant to be evicted from the Big Brother house on last year’s series of the Channel 5 show.

He will appear on new Channel 4 show “How Did You Get So Rich?” tonight, which sees comedian Katherine Ryan speak to wealthy individuals to discover the secret of their success.

A promotional video for the show features a clip of Mr Singh sitting in a black convertible, believed be the same car involved in last week’s incident.

He describes himself on his website as a “multi-millionaire with business interests ranging from photographic studios to restaurants to consultancy to hotels to new inventions”.

When contacted by the Standard, he said: “If I saw two people, and I thought there were firearms, I would have reported them as well.

“In the world that we live in with all the terrorism, if they didn’t take action, then think about what could have happened?”

The businessman said he was “pi**ed off” by the arrest, but added: “I’m still going to do the film. I think it’s a good film.”

Mr Moseley said “Little Bastards” was due to be released later this year, featuring appearances from former Irish bare-knuckle boxer Paddy Doherty and Judith Jacob, who played health visitor Carmel Roberts in EastEnders.

A Met spokesman said both men had been bailed to appear at Camberwell magistrates court on March 30, both charged with one count of possession of an imitation firearm.
