The Google Street View camera caught a snapshot of a police operation in Prague in Senovážná Street while moving right through the scene. Some images have been replaced by later shots, possibly to conceal a failure or a paranormal phenomenon – see the photos below.
Most images from 2009 showing the operation were replaced with later ones from 2011, which you see when you move up or down the street.
Officers advancing and apparently preparing a camera for documentation purposes.
Notice the ghost legs? If you move down the street to the left, this officer …
… morphs into a different man with a very suspicious space-helmet. A typical X-File case.
