The Pulaski County sheriff's office has arrested a fourth person in the case of a child injured by liquid drain cleaner allegedly used in making methamphetamine.
Brian Herrin, 36, was arrested Thursday at a residence on Caney Branch Road in southern Pulaski County, deputies said.
Herrin was lodged in the Pulaski County Detention Center on charges of manufacturing methamphetamine first offence, and controlled substance endangerment to a child second degree.
The charges stem from an incident at Herrin's home this month in which a 20-month-old boy suffered burns to his face when he tasted the caustic drain cleaner. The child was treated at University of Kentucky Chandler Hospital.

The boy's parents, Curtis Anderson and Brittany Helton, and Herrin's friend, Krystal Hampton, also face charges in the incident.
