Theft Description

The bike was locked to a rack in the Cambridge Railway Station bike park (the 3-storey one covered with CCTV, some cameras were right by my bike).  It was on the first floor close to the exit nearest the station entrance.  I left if around 2pm.  Returning at 8pm, I found my lock still attached to the bike rack, but the bike was gone.  The crime was reported to station staff and to the police.  The bike is almost new, less than a year old, and as such would be worth a good amount at resale.  Any information would be hugely appreciated.
