"As we explained in 'Underworld Economics: Why are so many bikes stolen?', bike theft is usually a low-return but low-risk activity (sadly). But once in a while, a thief will bite more they can chew and karma catches up with them. This recently happened in London where Ben Jaconelli's high-end GoCycle electric bike worth £2,500 (about $4,200 at today's exchange rate) was stolen despite the fact that it was securely locked and was left unattended for only 20 minutes."
