New CCTV images have been released showing a man suspected of being responsible for the graffiti-desecration of the £7.5 million Bomber Command memorial.
The man is captured moving in and out of shot next to the memorial, based in Green Park, in the early hours on Monday.
The monument to the 55,573 Bomber Command veterans lost in the Second World War, which was opened by the Queen last June, had the word “Islam” sprayed on it in red paint.
