Eighteen people face criminal charges after a huge drug bust in Northwestern Wisconsin.
The arrests come after an investigation on the Lac Courtes Oreilles Reservation in Sawyer County.
Prosecutors say in 2002 the tribal board asked state and federal officials for help to combat gang related crimes that were growing more deadly.
The suspects range from 20 to 48 years old. Their charges include distribution of cocaine and methamphetamine.
Four people have already been convicted in the investigation.
