Another arrest has been made in connection to a drug bust in Houghton County.
Earlier this week, 24-year old Charles Lester Knuckles was arrested at a residence in South Range after UPSET Detectives executed a search warrant which led to the seizure of prescription pills, suspected heroin and crystal meth.
Knuckles is now facing five felony drug charges.
Detectives say another suspect believed to be involved in the sale of heroin and morphine boarded an Indian Trails bus Thursday and left Hancock, bound for Detroit.
Authorities called troopers at the Michigan State Police St. Ignace Post for help.
As the bus made its scheduled stop in St. Ignace, troopers found the 26-year-old man from Houghton County.
He was arrested on a five count felony warrant for deliver of heroin and morphine and taken to the Houghton County Jail.
His name has not been released and additional arrests are pending as the investigation continues into what law enforcement are calling a drug trafficking organization.
