A structure fire was reported at a residence in the 500 block of East 8th St in Yankton late Friday afternoon.
Yankton Police Lieutenant Todd Brandt says two subjects were treated by EMS and released at the scene.
After the fire was extinguished, authorities found components of a one-pot meth lab inside the home.
Brandt says 25 year old Laray Lee Slate was arrested for Unauthorized Manufacturing of a Controlled Substance (class 4 Felony) and a Parole Violation.
The case was investigated by the Yankton Fire Department, Yankton Police Department and the State of South Dakota Division of Criminal Investigation.
