Police have warned of สล็อตออนไลน์มือถือ a new scam circulating on WhatsApp in which scammers claimed to be selling gold bars at cheaper prices to victims, who did not receive the gold after making payment.

The scammers communicated with victims using compromised WhatsApp accounts belonging to the victims' friends, said the police on Wednesday (Jun 2).

Victims were asked if they would like to purchase gold bars at a price 30 per cent below market rate.

The scammers claimed that the gold bars were being sold cheaply as they were seized by the Immigration and Checkpoints Authority or Singapore Customs and were being auctioned off, said the police in a news release.

The scammers provided a fake invoice purportedly issued by Singapore Customs.

They then instructed victims to transfer the payment to bank accounts they provided. Some victims were told to meet up with the scammers to collect the gold bars.

"Victims only discovered that they had been scammed when they did not receive the gold bars, or when they realised that their friends' WhatsApp accounts had been hacked after contacting their friends who did not turn up to complete the transaction," said the police.
