NSW Police have warned of a tax time phone scam accusing residents of tax evasion.
Hume Local Area Command officers have received numerous reports of a caller claiming to be from the Australian Tax Office demanding an immediate payment.
Police said the calls were made to home phones on Wednesday.
Crime Manager, detective inspector Chad Gillies said the phone calls had sparked anxiety among recipients.
"It appears the caller, who is male and usually has an Indian or Irish accent, claims that there is a debt owed to the Australian Tax Office," he said.
"As a result, the caller claims that a warrant has been issued for their arrest and a payment of funds is required in the next 12 hours to prevent further action.
"These phone calls have generated considerable anxiety within the community and some people have been close to transferring large amounts of cash."
Detective inspector Gillies said the caller had demanded between $4,000 and $20,000 and seemed to target older people.
"I believe that in one case it was only as a result of staff intervention at a financial institution that a large sum of money was prevented from being placed into the fraudsters account," he said.
"The vast majority of phone calls have been to people over the age of 60 so, it seems there is a deliberate attempt to target that demographic."
Detective Inspector Gillies urged anyone who received similar suspicious phone calls demanding money to contact their local police immediately.
