London police on Monday arrested four Greenpeace activists who climbed several iconic statues here to protest high levels of pollution in the British capital.
As part of their unique protest, the activists climbed statues such as Eros in Piccadilly Circus, and the statue of Oliver Cromwell and Nelson's Column and placed masks on them, Efe news reported.
According to the police, four people were arrested -- of them two while they climbed the statue of Oliver Cromwell within the grounds of parliament.
Greenpeace reported that the activists had targeted 17 statues in the city, including the figure of Queen Victoria outside Buckingham Palace.
This protest, according to the environmental group, aims to put pressure on the mayor of London, who will be elected on May 5, to take action against pollution.
