The yellow thumbtack graphic seen piercing the roof of Dr. Rey's L.A. pad was placed there by someone using the computer -- and judging by the thumbtack that marked burglary victim Orlando Bloom's house ... Dr. Rey may have gotten lucky.
Granted, Dr. Rey is a self-proclaimed black belt ... so his mad skills for whoopin' ass could have scared any potential burglars away.
Rey's wife tells us: "My body is shaking all over. It's so scary! Thank goodness they were caught ... I will have to add extra locks to our doors ... It's very scary that it is so easy to find where people live online."
