Seventy- five people across the metro area were arrested this morning in what is described as the largest drug bust in Colorado history.

Members of street gangs committing violent bank takeovers and other street crimes were identified as traffickers of massive amounts of cocaine, crack and methamphetamine.

Agents and officers from nearly every federal and state law enforcement agency were involved in the investigations.

Eighteen people are still at large. A total of 97 people are charged in state and federal indictments.

Eleven weapons, including an SKS assault rifle, an AR-15 assault rifle, handguns, $415,140 in cash, 26,129 grams of cocaine, 1,000 grams of crack and a pound of methamphetamine were found during the operation.

Twelve children were removed from homes where agents say drugs, guns and cash were stored.

The arrests are a culmination of four separate crime investigations that agents noticed were overlapping with the common goal of drug trafficking.

In December 2009, the FBI began investigating several violent takeover robberies in Denver committed by gang members as part of the drug trafficking organization.
