Scottsdale police are warning again about a phone scam in which callers are posing as department employees and demanding money to clear a warrant.

Authorities said scammers are using phone software to make it appear as if they are calling from the Scottsdale Police Department. They tell potential victims that they have a warrant, and it must be paid over the phone with credit or gift cards or money orders.

“The scammers try to convince you this is real, a very serious matter and threaten you will be arrested if you don’t pay them,” police officials said in a release.

“They may have personal information about you obtained through open-source internet and social media searches. Our employees will never ask for payment over the phone to clear a warrant.”

Scottsdale police posted a release on the department website several weeks ago regarding the same scam.

Individuals who receive such a call are advised to hang up and call the non-emergency Scottsdale police number: 480-312-5000.
