Columbia, SC (WLTX) - Federal agents say they've made "significant" drug and weapons seizures in the Columbia area following a lengthy campaign known as "Operation Pop Rocks."

The U.S. Attorney's office say on August 6, officers took six suspects into custody after serving multiple search warrants in Richland County.

The arrests came after a eight-month investigation that the government says focused on violent narcotics deals going on in the Columbia area. The Richland County Sheriff's Department and Drug Enforcement Agency started sharing intelligence on investigations taking place in the area, and released that several law enforcement agencies were making undercover buys of heroin and crack being supplied by the same drug trafficking organization.

Multiple federal agencies were involved, as well as the Columbia Police Department, Sumter County Sheriff's Department, South Carolina Law Enforcement Division, and the South Carolina Highway Patrol.

“The investigation and federal indictment are the products of significant coordination between federal and local law enforcement agencies, and represent the commitment of the United States Attorney’s Office to combat the heroin epidemic that our community is currently facing,” United States Attorney Beth Drake stated.

“This case serves as just one example of the ongoing efforts of local Narcotics Bureau detectives who will continue to work diligently, together with our law enforcement partners, to prevent additional overdose tragedies related to this poison,” said Richland Sheriff Leon Lott. “Working with our community, we will overcome the Heroin/Opioid epidemic that has plagued the entire country.”
