Stolen bikes

I don't know why I'm looking, it's eating me up but this guy - http://www.gumtree.com/london/84/35266384.html - has listed this bike three times now coming down from £200 to £125 anyone missing it?

I'm not sure that is stolen to be honest, its a conversion, rather large frame, and running on 27" wheels, so £200 was a high price to begin with.
His number doesnt come up multiple times when you google, so I'd tend to think this was actually legit. Although obviously I could be wrong
