The Drug Enforcement Administration is warning of a scam that has hit the Yakima Valley. Agent Selby Smith says the scam targets people who purchase prescription drugs on the Internet or over the phone. He says the scammers are posing as DEA Agents calling people saying that enforcement action will be taken against them for purchasing the drugs unless they pay a fine. Smith says purchasing pharmaceutical by phone or through the Internet is illegal unless specific requirements are met. If you do get a call, Smith says, just hang up. The DEA would not deal with the situation over the phone.
