My friend just told me this was the guy that conned him .....
Conned his hp and money claiming that he sells Samsung Galaxy SII for around 700++(discount , sales all those shit) , my friend got interested and traded in his handphone and money to him .
Then after that , this conman went off . Conned my friend at Mines Shopping Center .

Well , all happened when my friend was taking KTM home after his lecture class finish .... then this guy came to him and explain to my friend that he owns a handphone shop in Mines , mentioning that today is last day of sales . Then he asked my friend what kind of handphone is he(my friend) intrested , then my friend asked him how much the price for Galaxy SII , he told my friend it's around RM 700++ , my friend got kinda interested (at that time he was not thinking if the guy was conning him , as previously he had bought stuffs like this before ) and followed him to Mines .

Then once my friend and that conman reached Mines , the conman told my friend to wait (need to check supplier lah , this lah , that lah) , then he brought my friend to a corner and told my friend to give his handphone and money (to trade in for SII) and he'll go and take the SII for my friend .
After giving the handphone and money , the guy went off , leaving my friend alone .     

It's because that he previously had encountered something like this before and it was real (I think he mentioned bout computer)
