The Ministry of Foreign Affairs Wednesday warned citizens against dubious trade deals offered by some people pretending to be officials of fictitious foreign firms. An official source at the ministry said that recently some gangs pretending to be bosses of foreign firms or their authorized representatives have managed to drag Saudi citizens to deal in false trade. “Using SMSs and telephone calls from outside the Kingdom and unknown trading titles, the tricksters claim to be dealing in gold, precious stones and other metals,” the source said. Such deceptions, the source said, threaten security and safety of citizens, exposing them to kidnapping and detention and extortion of money. All citizens should beware of falling into such traps, the source added. The ministry explained that no citizen should deal with such parties unless obtaining a green light from respective Saudi embassies abroad.
