Theft Description

I locked my bike to a parking sign post outside my address with magnum d-lock. when came out next day, the parking sign had been remooved from the post ,so i assume the bike with lock has been lifted of the pole,as lock was gone aswell. Its a well lidt street with terraced houses, had in my wildest imagination not imagined thiefs would have the nerve to do that, but then again i come from denmark,where there are more bicykles than inhabitants,where u can almost leave ur bike unlocked when u go shoping etc. i thought i had taken my precautions now that its my fifth bike stolen here in ten years.
