He has wa rushed to hospital in Kisii for medical attention.
Toto did not pick calls when contacted for comment.
A video from the scene showed the disabled who turned up to receive wheel chairs from Toto scamper for safely.
Members of the public who had turned up also fled in various directions as chaos ensued.
A tent erected for the event was pulled down as skirmishes sent the attendees off.
Journalists invited to cover the function also fled as skirmishes engulfed the place.
