Two people were arrested at the third day of protest around the Bilderberg Group meeting, which drew more than 2,000 people.

Police said 2,012 demonstrators congregated in the grounds of The Grove hotel on Saturday to listen to speakers such as former BBC presenter David Icke and US radio presenter Alex Jones.

Hertfordshire Constabulary confirmed today two arrests were made for a drunken disorderly behaviour and another for breaching the terms of the road restrictions around the venue.

Prime Minister David Cameron, Chancellor George Osborne and shadow chancellor Ed Balls were among the guests attending the secretive meeting, which also included leading figures from world politics, banking, technology and academia.

Today police said the operation around the three-day protests, which started on Thursday, had been a “very successful”.

Assistant Chief Constable Alison Roome-Gifford, who was the lead officer for the operation, said: “Between Wednesday June 5 and Sunday June 9 Hertfordshire Constabulary oversaw the very successful policing of the Bilderberg conference.

“The policing operation was designed and planned with the strategic intention to strike a balance between the rights of the public to hold peaceful protest, the safety and security of the conference and its delegates together with the right of the local community to go about their lawful business.

"Along with all other police forces in the country Hertfordshire Constabulary has a core policing duty to prevent crime, maintain the Queen’s Peace, protect the public and prevent damage to property."

Hertfordshire Constabulary said it was still counting the cost of the large security operation, which saw officers called on from other forces such as Essex, the City of London and Thames Valley.

The force confirmed organisers of the Bilderberg Group meeting were contributing to the costs and that it was also in negotiations with the Home Office over securing a grant for the operation.

Assistant Chief Constable Roome-Gifford added: “The total costs of the police operation are still being finalised, but details will be released as soon as they are known.”
