Scotland Yard has launched an investigation after five memorials and statues were attacked by vandals in what appears to be a coordinated campaign.

The first incident, which caused widespread public anger, occurred on Sunday night when white paint was splattered over the memorial to Bomber Command in London’s Green Park.

But it later emerged that three other war memorials and plaque a murdered police officer had also been targeted at around the same time.

The targets included the Allies Statue statue of Second World War prime minister Sir Winston Churchill and his US counterpart Franklin D Roosevelt in New Bond Street, the Canada Memorial in Green Park, and the Royal Marines Graspan Memorial on The Mall.

The memorial to Yvonne Fletcher, the police officer who was murdered by a gunman during the 1984 Libyan Embassy siege, in St James's Square, was also attacked.

In each case white paint was splashed over the statues and police have said they believe all the incidents are linked.

No arrests have been made and police have said it is not clear what the motive behind the attacks is.
