Is this bike stolen?

The market stall holder asked for £85, they get some of their stock from lock up auctions and storage clearance down there, I thought he obviously doesn’t know what he has, or it is stolen. But it now seems the bike was only stolen two days ago from the owners garage, along with a carbon fibre race bike. So if he was selling it for £85, he must have given pittance for it. Cheekily I offered him eighty. Five minutes later I was sat in front of my laptop checking the stolen lists & speaking with Condor.
