i dont personally agree with the name and shame business usually, however in this case I think you should at least tell Stu or Pet because this person is using PF as a place to sell his stolen goods (ok, so were only sure of this item, but its likely not to be the only 1) and each and every one of us could be the next person to get ripped off.

cant the police still do people for receiving stolen goods?? if so and you back out of giving them it now they could do you for it?

if the above is right (and i'm not sure at all if it is), i actually dont think you have a choice in your next move tbh
