Authorities in northeast Tennessee say they found 10 pounds of methamphetamine when they stopped a pickup truck.
Washington County Sheriff's Lt. Doug Gregg said it's probably the largest meth seizure in East Tennessee and is valued at $448,000.
The Johnson City Press reported the truck was stopped May 14 after suspects had been under police surveillance.
Police said those arrested were 35-year-old Guadalupe Granado of Newport; 33-year-old Marcos Antonio Rivera of Winston-Salem, N.C.; 29-year-old Mendoza Ventura Placido of Galax, Va.; 37-year-old Abel Martinez Tavera of Winston-Salem, N.C.; and 30-year-old Elias Mazariegos Perez of Morristown.
The investigation that produced the arrests began in March after the conclusion of Operation Talisman -- a massive 2009 drug investigation.
