A gang of robbers targeting bank clients was arrested here on Sunday. The gang's modus operandi was simple: An African member of the gang would loiter in the bank premises mingling with clients and passing all information to gang members outside of the money transactions. Upon getting the signal about a potential target, those outside the bank will pounce on him and steal whatever they could from the helpless bank client. The “strange bank client” was kept under surveillance by Jeddah Police in several banks. And he turned out to be the kingpin of the gang, Okaz reported on Monday. An African woman, a legal resident here, turned out to be the one remitting the stolen amount abroad for the gang. All have been arrested. The Criminal Investigations Department (CID) of Jeddah Police have also found out that an African woman was cooperating with several other gangs in sending the looted amount abroad. The gang was busted after CID sleuths kept a close watch on the African in one of the banks. It was noticed that the alleged culprit was there for a long time amidst clients. The sleuths followed the man to another bank where again he stayed for a long time without transacting any business. After watching the clients for some time, this “strange client” left the bank. Soon the sleuths pounced on him and arrested him with three of his aides.
