They spoke to him and were convinced that he had bought it in good faith, so it was his bike. [b]he shouldn’t be arrested for receiving stolen goods.[/b]
FTFY.
I don’t know enough about law to be sure, but common sense (yes yes, I know) would dictate that it can only be “his bike” legally if the seller was legally entitled to sell it in the first place? Surely?
Otherwise, I could rock on up to someone, say “that Mercedes outside? Give me the keys, it’s mine now, I’ve just bought it in good faith from a bloke in the pub.”
