Officials from the Yavapai County Sheriff's Office say they have been investigating several cases involving pills and tablets containing fentanyl in recent weeks.
According to YCSO, within the last week, detectives from Partners Against Narcotics Trafficking (PANT) seized several capsules which are believed to contain fentanyl pending further lab testing.
Officials are asking the public to remind their families about the dangers of drug use with fentanyl-laced pills available in their community.
"It is very important that teens understand the life-threatening risk of sharing pills at parties, and how drug experimentation can have fatal consequences," YCSO said in a news release.
Authorities say PANT investigations are ongoing with the goal of arresting suspects involved in the distribution of fentanyl.
