Lethbridge police says the caller claims he's a member of the force and then tries to solicit funds.
A resident called police to complain that he's been called more than six times in the past few days.
The caller provided a fake name, fake badge number, and told the person he had won $2 million from a lottery and that he had been defrauded.
The caller said in order for the man to get the money, he had to pay $35,000.
Police say this is an advance payment fraud and remind the public to never send money to strangers and always be wary of prize schemes.
