Houston freeway Scammer Rich dubai guy

watch for scammers selling fake gold for money. They are claiming they are from dubai or some where wealthy. They are parked on the side of the freeway waving down people. Supposedly lost their wallet etc. Have been seen also in stores as well. Will use their own family to bride you. I seen them for the third time around 610 and I-10 east. I didn't get to take a pic. I believe they rent out cars as well but have been seen in a tahoe or yukon. So far its been two guys and a woman with a kid.
