Rudisha and KTN News launched a prank campaign that tricked many viewers into thinking that the Kenyan 800m world record holder had collapsed on air during a live interview.
The aim of the campaign was to increase awareness and educate Kenyans about the importance of giving way to ambulances on the roads and also importance of ambulance Services.
