SINGAPORE - Five Malaysian men have been jailed over a credit card scam on Sentosa Island.

The men, aged between 20 and 38, were convicted between April 18 and May 9 for making fraudulent online purchases of tourist attraction tickets with stolen credit card details.

The police were alerted when they received several reports on November 18 that redemption letters for tickets bought online with stolen card details were presented at attractions on Sentosa Island.

Mohamad Shafiq Bin Arzemi, 21, and 20-year-old Muhammad Ariff Bin Mustaffa were arrested on the island later that day and two counterfeit cards recovered.

Further investigations established the identities of their accomplices: 38-year-old Sia Chung Boon, Rafiuddin Bin Suddin, 22, and 20-year-old Muhammad Amirulzaman Bin Kamaruzaman.

They were arrested at the Tuas Checkpoint when they tried to leave Singapore on the same day, November 18.

The men were jailed on charges of abetment by conspiracy to cheat and abetment by intentionally obstructing the course of justice.

Sia was sentenced to 19 months' jail; Rafiuddin for 14 months; Shafiq for 11 months.

There was an 11-month term handed down for Amirulzaman and and 10 months for Ariff.

Police advised merchants to adopt verification standards such as requesting copies of the creditor debit card and identification documents to ensure that purchases are made by the actual cardholders.
