So I got my letter from the Police with my case manager's name and the incident number. And the next day I got another one, saying "case closed, we're not doing anything".
So there we go.
Despite there being a load of CCTV up and down the street and a gazillion witnesses, that's it.
In the mean time, the guys at Evans are being great still; new forks and handlebars are on the Felt, I just need wheels to arrive now. Apparently it looks pretty good.
