Stolen bikes

The strangest thing was, my heavy duty Kryptonite U-lock seemed completely undisturbed. It was still locked to the rack when I found it, no damage at all. Anyone know how a thief would take a Brompton from that?!

Brompton's can come apart at the folds and front wheel+forks+bars removed if they have the right tools and know how then slide it out of the lock. If you get a replacement then buy a bag and fold it up to bring inside with you, even when well locked up the things are theif magnets. Sorry for your loss.
