According to PW.1, A2 dragged the deceased from the panchayat office and A1 hacked him with a knife used for cutting of goats and when the deceased fell down, A1 also cut the pikkalu of the deceased. But he did not state anything about the specific overt acts of A2 except dragging the deceased out of the panchayat office. PW.1 has given the complaint to the police, which is marked as Ex.P-1. In the said complaint, he has stated that A2 caught hold of the shirt collar of the deceased, who was sitting on a corner of the warandah of Grampanchayat office and was pulling to a distance and A1 stabbed with a knife, which is used to cut the bags, he sustained bleeding injury and fell down and inspite of that he did not stop causing injury, in the meantime A2 picked up a stick and beat the deceased. Even though PW.1 in Ex.P-1 stated the specific overt acts of A2 but did not state in his evidence. As already observed above, PW.2 has stated about the specific overt acts of A2 in beating the deceased. But according to Investigating Officer PW.15, PW.2 did not state the same in the statement under Section 161 of Cr.P.C. and it is an improvement made by him during the course of trial. As such the evidence of PW.2 with regard to A2 beating the deceased with a stick cannot be believed. PW.5, another eye witness, did not speak anything against A2. Therefore, there is no material on record to show that A2 has beaten the deceased except dragging the deceased from out of the panchayat office. Even with regard to dragging of the deceased from the panchayat office, the investigating officer PW.15 in his cross-examination has stated that PW.1 did not state before him that A2 dragged the deceased into the bazaar but he stated that A2 dragging the deceased and he further stated that PW.2 also did not state before him that A2 dragged the deceased from the office but stated A1 was dragging. Therefore, even the evidence of PWs.1 and 2 with regard to A1 dragging
