Google's Street View cameras have been accused of many things, from helping robbers case their targets from the comfort of their armchairs to snapping errant husbands strolling out of strip joints.
But the explosive power of the online mapping service reached a new level when one Google driver came face-to-face with an armed policeman outside a high-security nuclear power plant.
The picture taken captures the moment the officer, who was armed with a high-powered rifle and dressed in black, approached the vehicle at a loading depot near Dunbar, in East Lothian.
Internet enthusiast Alan Turnbull, 56, spotted it while researching Scotland on Google.
He said: "I was just having a browse on Google maps when I came across this fascinating picture.
”It is such a coincidence that the Google street car came along to take pictures at exactly the same time as the nuclear shipment. It is quite funny really."
Google denied it had breached any security measures.
Spokeswoman Laura Scott said: "Google only takes images from public roads and this is no different to what anyone could see travelling down the road themselves, therefore there is no appreciable security risk."
The Civil Nuclear Constabulary said officers carried out "routine duties"
