Sand Springs are warning residents who have recently received phone calls that appear to be from Sierra Leone, or another country, to not answer.
Police say they think the calls are tied to the "wangiri" scam, where the original call is placed by an auto dialer, and when you pick up, it disconnects, or a message may otherwise ask you to call back.
Do not call back, police say. It is an attempt by scam artists to collect money.
"Our best advice is to screen your calls, and do not return calls to unknown numbers out of curiosity. You can also call your phone provider to ask about other technology they may offer to help reduce these nuisance calls," police said.
