A child accidentally drank drain cleaner, according to the Pulaski County Sheriff's Office, which led to the arrest of the 20-month old boy's parents.
Investigators said the child drank 'liquid fire' from a cup at a neighbor's home and burned his mouth, face and chest as he dropped the cup.
Investigators arrested the child's parents, Curtis Anderson and Brittany Helton.
Investigators said they had warrants out for Brian Herrin and Krystal Hampton.
Investigators said the incident happened at Herrin's house and that he faced meth charges.
