The family of the deceased claimed that Fiaz was innocent and he was the father of three children. The DPO said that six officials were held under the murder charge while SHO Malghani and other officials were nominated for negligence. On Saturday, the medical report was issued where doctors said that Fiaz did not die from torture.
