I feel pity for the innocent guy that might still be in police custody due to his mistake and ignorance, such situation have put a lot of innocent people out there in a big mess. That's why I'm the last person that would patronise fairly used gadgets, I love to buy my gadgets from  the slot or a recognised gadget store where I'll be sold brand new devices and issued the appropriate receipt for the items. And that's cause I've heard awful stories of people that's been victims of the same circumstances therefore I've learnt from their experience.
 The recent one of them all was when a guy shared some experience of how he almost got into police custody cause of a stolen item. In his own case he was neither the buyer nor the seller, but was an apprentice for a  phone repairer who happens to be the third buyer of the stolen item. The actual item was stolen from a rich fulani merchant whose brother was in the Nigerian army and sold to two other people before it finally got to the phone repairer.
 Luckily for the guy narrating the story he was able to escape when noticed some military men grab his boss, they intended taking everyone in the shop with them to the guard room but luck was on his side that day. However buying a fairly used property can be very risky due to such situations and people that indulge in such act needs to be very careful not to buy the wrong item.
