Fargo police warn of tainted heroin after overdose deaths

Police are warning about possibly tainted narcotics after a rash of overdoses in Fargo and neighboring Moorhead, Minn.

Authorities have responded to at least four overdoses in the past two weeks in which three people have died.

Fargo Police Chief Dave Todd says the drugs may be laced with other chemicals that make them especially dangerous. Todd says it's possible that heroin is being laced with narcotic painkillers such as fentanyl or morphine.

Todd says four people arrested early Sunday at a south Fargo motel are believed to be a source of the drugs.

KFGO-AM reports at least two of the suspects have ties to the Twin Cities area, where police say a lot of the opiates are "channeling through" before they reach the Fargo-Moorhead area.
