Four people face federal charges following a drug bust that netted 31 kilograms of cocaine and about $2.4 million in cash.
Local and federal officials held a press conference to announce the charges at 4 p.m.
Officials said they disrupted a major cell of drug distribution in Baltimore, cutting off a major source of supply.
Rod Rosenstein, U.S. Attorney for Maryland, said the investigation began in August 2015. Investigators received a tip that a major cocaine ring was operating out of a warehouse in Baltimore.
On April 8, agents stopped a truck leaving the location and discovered the cocaine. They recovered the money from the home of one of the defendants.
"This case illustrates how large quantities of drugs are brought into this region," Rosenstein said.
