SCAMMERS posing as cops are making threatening calls from numbers that appear from Queensland Police.
A Queensland Police Service spokesperson said scammers were using caller ID spoofing as part of the con.
The technology enabled criminals to manipulate telephone networks to make calls look like they were made by police.
The spokesperson said the scammers were threatening to arrest those who did not make payments using gift cards.
"The scam starts when the criminal calls the victim impersonating a government department," the spokesperson said.
"They advise the victim has an outstanding fine or fee with them.
"While this type of scam has been doing the rounds for some time, police are concerned this version of the scam has an additional layer, which may result in more members of the community falling victim."
Financial and Cyber Crime Group Detective Superintendent Terry Lawrence urged people to be careful when answering unsolicited calls that asked for money.
He said no government agency, law enforcement or any legitimate organisation would ask for gift card payments.
"We want you to be on your guard and we want you to question anyone who asks you for money," he said.
"The biggest fault in this scam is that they ask you to pay the fee or fine in gift cards."
Those with information about the scam contact Policelink on 131 444 or make an anonymous report to Crime Stoppers on 1800 333 000.
