Reports have been received of scammers calling households from what appear to be trusted NSW Police Force numbers and threatening the call recipients with fines or arrest.

These scammers are using technology to make it appear the calls originate from legitimate police phone numbers, a practice known as ID spoofing.

The caller impersonates a NSW Police Force officer and states that the person receiving the call has an outstanding fine or warrant.

The scammer demands a form of payment to prevent arrest or further court action.

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.

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, a spokesperson said.

"If you're concerned, you can always verify by contacting Forster police 6555 1299 or the Police Assistance Line directly on 131 444."
