My Stolen bike was returned to me, last night. I'm lucky! from what I understand there are something like 300 stolen bike sat in Kings Cross Police station and a new team has been set up to try and get them back to their owners.
Mine was stolen on 9th of December, ridden 2 Miles from my house and abandoned on a housing estate. The police picked it up that night. It sat in kings cross for like 6 weeks. I think I was fairly lucky as it was a fairly distinctive Neil Orrell so they linked it to the police report.
Good luck to finding your bikes everyone.
