Scammers have been using a phone number that appears to belong to the Criminal Investigation Department (CID).
The police said yesterday that members of the public have received calls from a telephone hotline number 6435-0000, which belongs to the CID.
"The calls were made in both English and Mandarin through an automated operator system," said the police in a statement.
They clarified that the calls were not made by police officers.
Instead, such calls use typical scamming tactics where caller ID spoofing technology masks the actual phone number while displaying a different number.
The police advised the public to take the following precautions if they receive calls via such automated operator systems:
• Ignore the calls and the callers' instructions.
• Do not provide your name, identification number, passport details, contact details, bank account or credit card details or other banking information such as usernames and passwords.
• No government agency will request personal details or money transfers over the phone or through automated voice machines.
• When in doubt, visit www.scamalert.sg or call the anti-scam helpline on 1800-722-6688.
