Update by OP. Just had a bike Chase!!! The thieving moronic twat was only riding the bike 100m (from where he stole it!!! My missus was driving the kids back from a friends house when she saw my bike (it's pretty unique) and gave chase but the little daffodil gave her the slip down the warren of alleys on the council estate where he must live. Unbelievably when she came back and told me I then went out on my other bike him and his scally mates then went past me! I yelled some abuse at them and gave chase but because he knows the alleyways I lost him, which I found particularly affronting. Anyway, pretty sure I know which road he lives on so will now just ride up and down his road until I catch the thieving twat.
