DULUTH, Minn. (AP) — Duluth police report five people apparently overdosed on heroin over the weekend, and one of them died.

Officers responded to four heroin overdose incidents between Friday and Sunday.

Duluth police say similar reports of overdoses and increased heroin potency are happening in Minnesota and nationwide. Over the past year, Duluth police say they have tried to crack down on the trafficking, sale and use of prescription painkillers and heroin.

Investigators are investigating the recent overdoses. Anyone with information is asked to call the Lake Superior Drug and Violent Crime Task Force.
