the famous venue for UK grassroots football, which was the scene of an invasion of unexplained symbols on Monday. . . .Hackney Marshes became the latest venue to be struck by mysterious signs and symbols on Monday when a three-metre football gouged one of the 82 pitches at the London-based grassland.
Witnesses at London's amateur league football hub reported seeing a giant circle formation featuring a ball in the centre of the design – the same emblem that was seen as a hologram on Rio de Janeiro's Sugarloaf mountain on Sunday.

Even more curiously, the mysterious circle was broken by the 3m football-like object that left a gaping hole in the ground – resembling the effect of an aerial crash landing.
Dog walkers also reported smoke emanating from the sight for hours on Monday morning before the area was later cordoned off.

Two thousand smaller footballs - each containing the same cryptic logo – were scattered around the football pitches of Hackney Marshes.
Locals were left stunned by the sightings. Retired builder Michael Pimmer, 74, was walking his dog at sunrise. “I have been visiting these fields for many years, but I have never been left awestruck like I was today. It was truly bizarre."http://m.goal.com/x/en-ng/news/4350028
