About a year ago my old bike was stolen by cutting through the fence that I had locked it too (I didn't realize that the fence was thinner than the lock itself) and now I've come across it once again whilst on a jog and checked the serial number and it was the same as my old one. I've contacted the police and they said they don't have any legal power of cutting through a lock, so what am I supposed to do?
The bike hasn't been used in a while as there are cobwebs on it and tires are flat, so I don't suspect I'll find the new owner anytime soon.
Edit - Forgot to say that this was in London
