SUDBURY -- Greater Sudbury Police is alerting public about a new phone scam in which the caller appears to be phoning from police headquarters.

"We have been receiving complaints from community members that scammers have been spoofing the GSPS phone number (making it appear in caller ID) and demanding bitcoin payment for outstanding arrest warrants," police said in a tweet Thursday.

"Please be reminded that the GSPS does not demand payment."

The scam is the latest in which fraudsters pretend to be police and try to convince people they have to send them money.

On Wednesday, North Bay police warned of a scam  in which callers pretend to be local police and say a loved one has been in an accident and they have to send money to help them.

And since a Nova Scotia man dressed as an RCMP officer committed a mass killing in April, there has been a rise in similar incidents across Canada.
