The hackers’ collective Anonymous may have obtained “literally explosive” information concerning Bohemian Grove, an annual gathering of power brokers from the US and Europe set to meet this week in California, which many see as a nefarious avenue through which elitists secretly manipulate world affairs.

Bohemian Grove is a privately owned 2,700 acre compound in Monte Rio, California surrounded by giant old-growth redwood trees. Once a year it plays host to a bizarre confab attended by some of the most powerful people in the world, including many US politicians and government officials, during which participants embroil themselves in a heady mixture of plutocratic plotting and occult pagan ritual ceremonies.

The Anonymous hacking group, which has already announced its intention to occupy the entrance to the Bohemian Grove compound as a protest against the group’s secrecy, may also be about to leak a whole treasure trove of information about the organization as part of what has been dubbed “the biggest day in Anonymous’s history”.

As part of a series of hacks conducted to protest the treatment of Wikileaks founder Julian Assange, to whom Anonymous has attached itself, the collective says it is about to unleash “literally explosive” material on a number of organizations, including the London Metropolitan Police and other agencies connected to the UK judicial system.
