The minor boy, Golu was branded with hot iron rods and tied upside down by his step-mother Manju and his father Vijay as a punishment for his habitual bed-wetting, according to a complaint lodged with police on Tuesday.
The complaint was lodged by a social activist who helped in rescuing the child.
The accused -- Manju and Vijay -- also confined the boy in their house in Lohegaon area for three days from November 9 before neighbours came to know about the inhuman torture after hearing Golu's loud cries, leading to police intervention.
A case was registered against the couple under relevant sections of IPC and Juvenile Justice Act.
Golu, who is in a state of shock, is undergoing treatment for burn injuries all over the body in a hospital.
