VANDALS who defaced the Bomber Command war memorial are also believed to be behind an attack on a plaque dedicated to murdered police officer Yvonne Fletcher.
Three other memorials have also been targeted since the Bomber Command tribute was daubed with paint on Sunday night.
The tablet marking the spot outside the former Libyan embassy where PC Fletcher died was sprayed with white paint some time between Sunday and Monday.
Police said their inquiries were moving ‘at pace’, as they examined forensic evidence and CCTV footage. But they are urging any witnesses to come forward.
The Police Federation, which represents rank and file officers, tweeted: ‘Please help us find the subhuman scumbags who did this to the memorial to our murdered colleague.’
The 25-year-old officer was policing a demonstration outside the embassy in St James’s Square in April 1984 when she was hit by a volley of shots — seemingly fired from inside the building.
Home Secretary Sajid Javid hit out at the perpetrators behind the Bomber Command attack in Green Park, London.
‘A totally disgusting and despicable act that disrespects the memory of those who made the ultimate sacrifice for our country,’ he tweeted.
The Bomber Command memorial to 55,500 Allied servicemen who died during World War II has been vandalised four times since it was unveiled by the Queen in 2012.
Air Vice-Marshal David Murray, chief executive of the RAF Benevolent Fund, said: ‘This is the worst vandalism we have seen. It is utterly heartbreaking to see the memory of all those brave airmen disrespected in this way.’
