Police are urging the public not to send money to fraudsters posing as TV Licensing officers.
Emails doing the rounds recently claiming to be from the Licensing Authority have been found to be scams, officers said.
The emails ask people to follow a link and provide personal information, including bank details. The fraudsters then call the person and try to encourage them to send over cash.
Police say anyone who receives this sort of correspondence should report it to authorities.
In a post on Facebook, a spokesman for GMP's Bury North team said: "Emails are being circulated pretending to be from the TV Licensing Authority.
"They want you to click the link and provide your telephone number and bank details.
"They then ring you and convince you to send them money to a safe account or hand over details of your bank card reader.
"Do not respond to these emails, do not hand over bank or personal details, no honest person will ever ask you to put money in a 'safe account'."
If you wish to report a suspected scam, ring Action Fraud on 0300 123 2040 or Crimestoppers on 0800 555 111.
