Traders are being warned to be vigilant in dealing with unregistered persons wanting to trade with large sums of money.
This follows a report where a Director of a vehicle spare parts company discovered a cheque close to $90,000 to be dishonoured.
Earlier this month the victim received a cheque from a woman in her late 30s who were wanting to buy vehicle parts.
A cheque worth more than $89,000 was exchanged for the parts but later discovered to be dishonoured when deposited.
A team of officers in the Southern Division were tasked with the investigations whereby they arrested the woman and her husband who are now being questioned at the Valelevu Police Station.
Investigators have also made recoveries from a vacant house in Nadi yesterday.
Police are urging traders to be cautious when trading with large sums of money and to verify details before exchanging goods.
