MEMPHIS — Twenty-five people have been indicted after a large drug bust in Memphis.

The Memphis Police Department and Shelby County District Attorneys Office announced the seven month operation on Thursday.

25 people have been indicted on various felony drug and conspiracy charges.

Police also say a letter carrier with the U.S. Postal Service was helping a gang sell drugs.

The carrier has been identified as Letravius Shaw.

Police say the bust involved the Grape Street Crips, the Travelling Vice Lords, and the Gangster Disciples criminal gangs.

The bust included heroin, Fentanyl, cocaine, marijuana, and Oxycodone pills.

Operation “Wait a Minute Mr. Postman” ran from August 2016 until February.

Thirteen guns, 33 vehicles, three motorcycles and $22,000 in cash were seized.

Last check with Memphis Police 14 people have been arrested, 11 are still outstanding.

“You often hear us talk about gangs, guns and drugs and this is an incredible visual of that intersection,” said Shelby County District Attorney Amy Weirich.

Organized Crime Unit officers said Shaw was willingly to help a gang member bring illegal drugs into Memphis through the postal system.

“We see that the drug epidemic touches all types of people. We have all types of individuals involved,” said Memphis Police Director Mike Rallings.

Rallings and Weirch said the bust is part of a ripple effect.

“I think it bears stressing that we may never know how many individuals in our community died as a result of this poison nor may we never know how many lives have been saved today by removing this poison from the streets,” Weirich pointed out.

Investigators say four of the people indicted were also responsible for stealing and reselling Oxycodone pills from a pharmaceutical company warehouse where they worked. Some of the thefts going back to 2013.

While Thursday marked a win for department getting more bad guys and drugs off the streets, Director Rallings said there’s still a long road ahead, asking for help from lawmakers in Nashville and the impact of allowing guns in vehicles.

He said he also needs help from people in Memphis and Shelby County.

“We need everybody on board to fight the infiltration,” he said.
