Presque Isle police warned heroin users that a bad batch of the narcotic led to five overdoses within a four-hour period on Tuesday.

A 6:30 p.m. Facebook post by Police Chief Matt Irwin said the first overdose was reported in the afternoon around  2 p.m.

“We are reaching out to everyone tonight who may have a loved one who is addicted to heroin in the Aroostook County area or maybe YOU are the one struggling with the addiction,” Irwin said.

“It appears there may be a bad batch circulating in our area. Please call for help at the earliest possible moment.”

None of the overdoses were fatal, according to Irwin.
