SINGAPORE - If you receive a phone call from the number 999, ignore it and make a police report.

The police said on Tuesday that it has received six reports in the past week from members of the public who have received phone calls from the number '999'.

The callers claimed to be representatives from government agencies such as the Singapore Police Force, the Immigration & Checkpoints Authority, or the Ministry of Manpower. They asked for money to be transferred to them or for the receiver's credit card details. Of the six reported cases, no money transfers were made, said the police.

In a statement, the police said these calls are "typical scammers' tactics". "Government agencies do not call members of the public to request for any money transfers or credit card details," it said.

The police urged the public to be wary of such callers. Those who receive calls with '999' displayed as the caller should ignore them, report the case to the police, and not transfer any money to the caller.

Those with information on this crime can call the police hotline at 1800-255-0000, or '999' for urgent assistance.
