Billionaire Peter Lim has lodged two police reports after his name and images were used in online scams, his spokesman said yesterday.
The Singaporean investor is concerned that some have already fallen victim to the scammers.
One scam involved several fake Facebook accounts that claim to be the official accounts of Mr Lim.
However, Mr Lim does not have any social media accounts.
At least one person has been duped into travelling for a purported meeting with Mr Lim overseas.
Another involved a claim that Mr Lim endorsed investments in a cryptocurrency, and has claimed at least one victim. Mr Lim has not endorsed such investments, said the spokesman.
This is not the first time that such scams involving the tycoon have surfaced. Last year, Mr Lim filed a police report against online claims that he had endorsed certain investment methods.
"Mr Lim is concerned that unsuspecting members of the public may be misled by all these false claims and suffer personal losses," said the spokesman.
"Members of the public are strongly advised to protect themselves against these false and misleading claims to avoid becoming potential victims of such scams. Netizens should also refrain from circulating and reposting these false claims."
