Stolen bikes

Sounds like the council took your bike, they have a habit of chopping off bikes and leaving notes that get blown away - they have some by law that lets them remove the bikes as they could be bombs.. might be worth checking with the local plod and council

Good suggestion, I phoned up Westminster council but they said that when they sticker a bike they leave it for 24 hours before removing it. So it can't have been them in this case... I've also reported it stolen on Immobilise so if the police do find it they should contact me. Guess the next point of contact is the insurance company...
