A man was duped into making multiple cash withdrawals and handing the money over to two conmen in the belief he was going to win the lottery, police allege.
Investigators say one of the men approached a 65-year-old in a Campbelltown car park at around 10am on Friday last week claiming he had a winning lottery ticket that he could not claim because he had no identification with him.
"He then approached a second man in the car park and told him the same story," police said in a statement.
"The second man made a phone call, then claimed he had just confirmed the winning ticket with a lottery agency."
The second man then offered to buy the ticket from the first and split the takings with the 65-year-old.
The 65-year-old agreed and was driven to four different banks where he made "large withdrawals" and handed over the cash to the men, police said.
The alleged conmen gave him the ticket and asked him to pick up some medication from a chemist.
When he returned, they had disappeared with his cash.
The 65-year-old took the lottery ticket to a newsagent, but was told it was not a winning ticket.
Police have released a CCTV image of a man they wish to question over the incident.
In the photograph, the suited man is wearing a hat, sunglasses, cream jumper or vest and a pink collared shirt.
