These scammers are using technology to make it appear the calls originate from legitimate police phone numbers.

The caller impersonates a NSW Police Force officer, saying the person receiving the call has an outstanding fine or warrant and demanding a form of payment.

"The NSW Police Force will never call a member of the public and demand payment over the phone in order to avoid going to court or being arrested," a spokesperson said.

"If you get an unexpected call from someone who states they're from the police, and starts asking for personal details or threatens you, please hang up.

"If you're concerned, you can always verify by contacting your local police or the Police Assistance Line directly on 131 444."
