Police found 'slaves' and a luxury fleet of supercars worth thousands of pounds during a dawn raid on a travellers' camp this morning.

A total of 14 people have been arrested after more than 20 police officers seized 'potential victims of forced labour', a £155,000 Ferrari, a £90,000 Range Rover and a Bentley golf cart at sites in Cardiff, South Wales.

Three campsites, Shirenewton, New House Farm and Newport Road, were stormed at 6am and officers say they discovered a variety of offences had been committed.

Police seized a fleet of supercars at a caravan site in Cardiff this morning, including this metallic blue Bentley Continental golf cart - similar to the one owned by boxer Floyd Mayweather

They include alleged high-value extraction of electricity, high-value theft and money laundering and officers also seized a significant amount of cash as well as the fleet of supercars.

A metallic blue Bentley Continental golf cart, thought to be worth £20,000 and similar to the one owned by boxing world champion Floyd Mayweather, was found at the Shirenewton site.

Police also took away a red Ferrari California T and a white Range Rover Sport - and posted photographs of the fleet on their social media pages.

It was part of Operation Baracuda, led by South Wales Police and assisted by the National Crime Agency, Cardiff Council and British Transport Police, to crackdown on major crime in the city.

One officer said: 'It was more like a luxury car showroom than an average caravan site.'

Shirenewton is one of two residential gypsy and traveller caravan sites managed by Cardiff Council which together have over 80 pitches.
