DICKSON COUNTY, Tenn. – Over 100 people have been indicted in what’s called the largest methamphetamine investigation in the history of Middle Tennessee, according to WKRN News 2.

A massive raid was conducted early Monday morning as state and federal agents arrested some of those named in the indictment.

Reports said arrests took place in Montgomery, Dickson, Stewart, Robertson, Sumner, and Humphreys counties.

The investigation spanned multiple states.

The defendants are accused of conspiracy to sell meth over 300 grams, a felony.

At this time, 75 of 100 defendants are now behind bars.

Ten guns were seized Monday as well as 928 rounds of ammo, cell phones, and drugs.

The prior eight month investigation has already yielded 73 firearms, a quarter million in cash, and more than 13 pounds of meth.
