Nine law enforcement officers aboard the bus represented the state police, Hamlin Police Department and Lincoln County Sheriff's Department.
"We unloaded and secured the scene," Napier said. "There were two active meth labs."
The arrests were made without incident.
"It was too shocking once we rolled off the bus and started putting everyone in handcuffs," Napier said.
Once backup arrived, an estimated 16 law enforcement officers were on the scene.
Three people were arrested and taken to Western Regional Jail.
Jerry Maynard, 39, was charged with operating a clandestine meth lab. Mark Vance was charged with having precursors for cooking meth.
Jeremy Collins was arrested on trespassing charges linked to a previous warrant for causing problems at a local convenience store. Officers could not find sufficient evidence to connect him with the drug activities.
