Three Nigerian men and a local woman were arrested in Kajang on suspicion of involvement in the 'Nigerian Romance Scam' activities which resulted in losses of about RM400,000 early today.

Bukit Aman Commercial Crime Investigation Department director Datuk Acryl Sani Abdullah Sani said all the suspects, aged 28 to 32 years, were arrested in two raids at about 4am.

"The arrest of a local woman and a Nigerian man in a house at Taman Orkid, near here led to the arrest of two more Nigerian men in an apartment in Kajang at about 6am," he said in a statement here today.

Acryl Sani said the woman was believed to be impersonating a custom officer or forwarding agent while the male suspect acted as the mastermind by using a false Facebook account to lure victims besides managing the victims' cash deposits in a bank account.

He said also seized in the raids were cash amounting to RM10,000, 12 mobile phones, five ATM cards, three laptops, jewelery and a Perodua MyVi vehicle.

With the arrest, he said police had solved 24 cases in connection to fraudulent activities in several states, including in Melaka, Perak, Selangor and the federal capital.

The case was being investigated under Section 420 of the Penal Code for cheating, which carries a maximum jail term of 10 years and with whipping or fine, upon conviction, he said.
