According to police, the incident took place four days ago at Habshipur village in the house of one Yellaiah, against whom a land dispute case was filed by his brother Parshu Ramulu in Dubbak Police station in the district.
As ASI Mohd Pasha reached Yellaiah's house to question him, wife Renuka tried to drive him away saying her husband was not at home.
An altercation ensued when the cop saw the accused at home and caught him. During the quarrel, the policeman accidentally stepped on Yellaiah's baby, who was sleeping on the floor, leaving her injured, police sources said.
However, the baby died this morning while undergoing treatment at a local hospital.
Following this, irate parents and villagers staged a dharna at the Dubbak police station with the body of the little girl demanding ex-gratia and suspension of the erring ASI.
A case will be registered against Pasha soon on the complaint filed by the parents of the dead girl, police added.
