Police are warning about scammers who are claiming to be Calgary officers while stealing thousands of dollars in cryptocurrency schemes.

Police say that over the past several weeks, they have become aware of cases involving scammers claiming to be Calgary officers to convince people they owe thousands of dollars in legal fees.

Investigators say that in most cases the scammers claimed to be a family member who has been arrested and someone impersonating an officer demands money for lawyer fees in the form of bitcoin.

They say in some cases the scammers even spoof the phone numbers to friends or family members to make the situation appear legitimate.

Other reports include scammers posing as officers who are trying to help victims recover lost funds through a third-party agency in exchange for “an exorbitant fee.”

Calgary police say people can verify an officer’s identity by requesting to see a badge, as well as a badge number and a photo ID card.

People can also call the police non-emergency number to verify an officer’s identity.

“Scammers often use high-pressure and fear-based tactics in order to receive payment quickly,” Calgary police said in a news release Wednesday.

“Do not feel pressured to provide money to strangers and take the time to talk to trusted friends and family to verify the legitimacy of the situation.”
