A retired principal Ojedokun Modede was on Friday hacked by suspected herders in Igangan, Ibarapa North local government area of Oyo state.
Modede, who suffered serious machete cuts on his arm, was said to have been attacked on his farm.
But, the police in confirming the incident said it was in reprisal of an earlier attack on three herdsmen by youths of the community.
A source close to the victim said trouble started when a herder directed his cows to feed on the yam flour, which was spread on the floor for sun drying.
The retired principal was said to have, in anger, challenged the decision of the herder but was met by a resistant herder, who drew out his machete with an intention to strike him.
