A 41-year-old man has been arrested and charged after allegedly conducting an elaborate phone scam worth tens of thousands of dollars. NSW Police allege the man was involved in making fake phone calls pretending to be law enforcement or a financial institution - such as a bank - in order to obtain money from unwitting victims.

The man allegedly demanded payment from people on the receiving end of the calls and threatened them with violence or arrests should they not comply.

Police officers found a post office box in Granville which was allegedly being used to facilitate the scam.

The man was arrested yesterday attempting to access the mailbox.

Police executed a search warrant, seizing a shoe box allegedly containing $25,000 in cash.

A second warrant was also executed at the man's home on Boundary Street, where another $4,900 was found.

He was taken to Parramatta Police Station and charged with two counts of knowingly deal with the proceeds of crime.

He was granted conditional bail and will appear in Parramatta Local Court on Thursday.

Police have said the incident was a reminder to the public to never give personal information to unverified people over the phone.
