Underground ghost station explorers spook the security services | UK news | The Guardian:
From Holborn they noticed the rails turn rusty and saw piles of flyers collecting at the tunnel's edges. And then, like hikers who'd reached the best view from the mountain, they saw the forest-green tiles of the platform edge.
For the next four hours they photographed the ticket halls, deserted walkways and antique lift system. Like their other trips – to the roof of St Paul's cathedral, the London Olympic Stadium, Battersea power station – they were careful to leave things as they found them; graffiti is taboo for urban explorers. When the battery on their camera went flat, they got ready to leave. They were interrupted by a shout: "Get on the ground!"
CCTV operators had alerted British transport police, who had issued a terror alert. After infiltrating 200 sites across the city over 10 years and getting away with it, they were busted.
