The police have arrested two men who are believed to be involved in several cases of theft from automated teller machines (ATMs).
A statement said that the police were informed on Feb 25 of several unauthorised withdrawals made using cloned ATM cards and that some of these cards were detained by the ATMs.
The two suspects, aged 38 and 45, were arrested at Changi Airport on March 16.
A Straits Times report said that the suspects are believed to be Romanian. Theft is punishable with a prison term of up to three years and a fine.
The police also advises all ATM and credit card holders to safeguard their cards in crowded places and to be aware of their surroundings.
They are also advised to ensure that their ATM PINs are not exposed to anyone else when making payments using their cards.
