The investigating officer has been replaced in the case due to the delay in the investigation to nab the culprit and police have recorded statements of more than 20 rat poison vendors.
“No remnants were found in the house apart from a rat repellent that we had found at their second floor residence on day one. We checked a bottle but it does not contain zinc phosphide but is a herbal concoction,” an officer who was part of the probe said.
